2 vs 2.16 Ghz

I'm brand new to Apple and in the next week or so am going to purchase my Macbook Pro. I was wondering how significant the performance difference would be between the 2 Ghz and 2.16 Ghz processors and if it's worth the money. I'm excited to finally be entering the Mac realm and to begin creating and exploring on my Macbook. Are there any things I should be weary of going into this? I've heard there are some heat issues, magsafe problems, RAM issues, etc. Any and all knowledge and advice would be greatly appreciated by this novice.

well the 2.16 works out to be about 8% faster, is that worth the extra cash for you? for me it is bacause the CPU isn't upgradable so you need all the speed you can get
as for the problems, the heat issues seem to be (mostly) gone, but you should know that it is a laptop that is designed to run very hot, to hot for some people, and the metal case dosen't help
as for magsafe and RAM, i have seen very few problems with either, but RAM can easily get replaced
other problems, are a few arrive with dead airport that cause crashes, this requires a logic board replacement (i had one of these, and this seems much more common then bad RAM), also most whine to some degree, and you will have a very hard time trying to get that fixed as apple says its within spec, its a high pitch noise, that is quite and appears when idle, it annoys some people, but not others

Additional Information
Apple Hardware Test is included on the DVDs that are shipped with some Macintosh computers. If the copy on your hard drive becomes unavailable, use the DVDs to run Apple Hardware Test.
For Intel-based Apple computers that shipped with Mac OS X v10.5.4 or earlier, Apple Hardware Test is located on the Mac OS X Install Disc 1 and should be included with your computer.
For Apple computers that shipped with Mac OS X v10.5.5 to 10.6.7, Apple Hardware Test is located on the Applications Install Disc 2 and should be included with your computer.
For some Apple computers that shipped with OS X Lion, if Apple Hardware Test cannot be found on the hard drive, an Internet-based version starts up instead.
This doesn't work as the additional information statement says it should above. Could someone at apple give me an idea of where to get it or what the "REAL" solution is, since it doesn't work on an internet version which was confirmed today at the Genius Bar in the Apple store.
Please help me

Are you holding down the "d" key, all by itself, just after the system shuts down for a restart?
And how long did you hold it down?
I held mine down for about 40-50 seconds. Then I lookat at my routers WAN light and it was flickering so I let up on the d key.
If that does not work then maybe there is something wrong with your MBP. Is that the reason you want to run this test, something isn't right with your unit?

Airport Express extends 5 Ghz and 2.4 Ghz or just one at a time?

I recently switched my dual band Time Capsule to use different names for the 5 Ghz and 2.4 Ghz networks.
Will the Airport Express extend both or just one at a time, if so, which one will it extend?
I have two Airport Express modules, bought a long time apart, is there any difference in functionality and how do I tell them apart if this is the case?
All are running the most recent firmware version.

Welcome to the discussion area, Mike!
Will the Airport Express extend both or just one at a time, if so, which one will it extend?
The AirPort Express is a single band device, so it can extend either the 2.4 GHz or 5 GHz band, +but not both at the same time+. Since you have different names for the 5 GHz and 2.4 GHz bands, the Express will extend the 2.4 GHz band by default. Using AirPort Utility, the setup application for the AirPorts, it is possible to configure the AirPort Express to extend either band.
If you are perhaps thinking of extending the 5 GHz band, this can be a bit tricky because 5 GHZ signals do not travel effectively over distance or penetrate obstructions as well as 2.4 GHz signals. You almost have to have a line-of-sight relationship between the Time Capsule and the AirPort Express to be able to extend the 5 GHz band.
I have two Airport Express modules, bought a long time apart, is there any difference in functionality and how do I tell them apart if this is the case?
Look on the side of the AirPort Express for the model number in the small print. You'll need Model No A 1264 to be able to "extend". If you have the older Model No A 1084, that version will not be able to "extend" a wireless network, but you could use it to "join" the wireless network and stream AirTunes to the device.
All are running the most recent firmware version.
That would be 7.5.2. If you have the older version of the AirPort Express, the latest firmware version for that device would be 6.3.

I have a Mac mini OSX 10.4.11 Intel Core Duo, 512mb, 1.83 GHz with iTunes 9.0.3. What steps do I need to take to get my music library to my iPad. I dont think I meet the requirements to just upgrad to snow leopard and/or lion. I want the music I paid for

I have a Mac mini OS X 10.4.11, intel core duo processor (not core 2 duo), with 512 mb and 1.83 GHz processor. I only have version 9.0.3 of iTunes because it hasn't let me go higher, which I believe is because of the operating system. I want to get my purchased music from the Mac mini to a different computer (that has the latest version of iTunes) and also my iPad. The Mac mini does not meet the requirements listed to simply upgrade to snow leopard or lion. As far as I can tell. Forgive me if I am lacking here...this is new to me. What can I do to get the music transferred. I have invested alot of money over the past few years on all this music that I should be able to transfer. Thank you in advance if you can help me.

If you want to sync it to the iPad from that Mac, you need to upgrade it to at least 10.5.8.
If you want to copy the music to another Mac, you don't. Move the iTunes folder of the item in the Finder's sidebar over as you would any other folder. If you put it somewhere other than the Music folder, launch iTunes with the Option key held down and point it to that location.

MacBook Pro 8,1 – Intel Core i5 – 2.23 GHz (early 2011) New with OSX 10.6 – current on all updates.
I successfully installed rEFit. I used Boot Camp to install Win 7. All was great.
Then installed debian 6. Somehow after the debian install and restart (I know this sounds crazy) but I am now reduced to Win 7 only. rEFit is not present when rebooting nor is OSX or debian. Further, I am unable to force the install DVD to launch when rebooting, by holding C, D or F8. The Option key brings me to the grey screen with a padlock. I have attempted the root and local pw- no go. Restart holding D takes me to the windows boot manager. I have attempted several options within the Advanced Options; including – Repair Your computer, safe mode and “last known good config,” All of which did nothing.
I can see all my OSX files within win7. I tried to install the OSX within windows. Ya right, that did nothing..
I only desire to get back to OSX...
What are my options??

Yes, you royally hosed up your machine.
You should first try to get your files off, any way you can to a external drive.
Your going to need to hold c and boot from the disk that came with your computer and a couple of screens in under the menu is a option for Disk Utility.
Select your drive and Erase with Security Option Zero, format the drive HFS+ Journaled and when that's finished (about a hour or so) then quit and install OS X from the installer.
I hope this works, but I suspect it won't. Others have hosed their machines trying to use a Linux disk without proper partition formatting too.
Another option might be to use another Mac to c boot off the Snow Leopard disk and install OS X onto a external drive, take that to the problem Mac and try holding option and booting off of it to erase your internal drive.
You could replace the drive.

There was someone else around here who hosed their Mac with a Linux disk too. Try to find it.

Windows XP or Vista for use with Parallels on MacBook 2.16 GHz?

As described in my earlier post, I'm currently switching from my G4 PowerBook to a new MacBook 13" 2.16 GHz.
I'll have to use Windows parallel to OS X (plan to do that with Parallels Desktop) and would like to know what you recommend:
Windows XP or Windows Vista?
Vista should be better in security issues, however it should also consume much more ressources and thus run slower ... is that right?
What's your experience?
Martin
MacBook 2.16 GHz, 2 GB RAM, 120 GB HD (white) Mac OS X (10.4.9)

Hi Martin,
personally I favour XP over Vista (at least for now and the near future), because as you mentioned Vista a much more hungrier than XP and also because there are still a lot of applications which do not work correctly or at all in Vista.

I fear that you are trying to download OLDER Software on a newer Operating Sysytem Meaning that you need to Install the Latest Version of Adobe on the Newer Operating System for it to work Properly. Be sure to always check the minimum System Requirements.

Adobe CS3 Upgrade on 2.4 GHz MacBook Pro

I am planning to purchase the new generation MacBook Pro in about a month.
My question is about Adobe CS3. I currently use CS2 on an older G4 PowerBook because I could not deal with the performance dip on the older MacBook Pro (1.83 GHz with 512MB RAM). So I have a licensed copy of CS2 for PPC. If I buy the Upgrade Version of CS3 at a much reduced price, will the transition to Universal work on a MacBook Pro? No more Rosetta? Performance problems solved?
I realize Rosetta probably struggled with my previous MacBook's speed and lack of RAM. But I don't want to go through that hair-pulling again. I don't get into that advanced PhotoShop, etc. of CS3 but I'm willing to upgrade just to have it Universal and be more reliable. And, of course, I'd like to save the $800 on having to buy the Full Version of the software.
Thanks everyone for your feedback.
By the way, I had the same performance issue with MS Office for Mac. Almost 30 seconds to open Word! Anyone know if this becomes a non-issue with newer Macbook Pros??
1.8 PowerPC G5 3GB DDR SDRAM Mac OS X (10.3.9)

Your problem your your previous MBP was simply RAM. 512MB when trying to use CS2 products is simply insanity. If you opt for a new MBP with the standard 2GB, better still with an upgrade to 4GB, then CS3 will perform extremely well. RAM us hugely important and one of the biggest bottlenecks in today's hardware and software requirements.

WORKAROUND! - Sluggish Motion V 4.0.1 on Mac Pro Nehalem 2.97 GHz 16 Vcore

Hi guys, like several people on this forum and others I been very frustrated with the performance of both Motion.app version 3 and now Motion.app V4 .0 .1 (latest update) on my 2009 Mac pro Nehalem 2.97 GHz 16 Vcore 12GB with the ATI Radeon 4870 graphics card.
I have two workarounds that may be of assistance in relieving this issue. They work for me however before I discuss what they I'd like to set the scene.
Like many of us, I have trawled this forum and many others including COW and so on mostly relying on those 10-12 (the dozen or so) excellent tips from people like Mark Spencer and others. This includes the usual things like turning off rendering options that make heavy use of CPU/GPU etc.
Caveat: I'd also like to note here that this performance sluggishness has absolutely nothing to do (and is completely unrelated to) I/O performance nor is it related to memory usage. The reason I say this is because during some testing and the normal practice I keep all a Motion.app cache files (autosave, cached files etc) out on a very fast PROAVIO EB8NS disk array with ATTO R380 HBA onto SAS paths where this box is capable of over 450 MB per second measured with Kona system test tool. Additionally I have 12 GB of memory on this Mac pro which I assigned 70% of it to be available to Motion.app V4. The sluggishness Motion.app V4 is not manifest itself through the usual items such as excessive virtual memory page in/out or swap in/out activity. In fact in this scenario I describe below in my system when nothing else is running the former is non-existent! Additionally I also want to know that Motion.app V4 in my scenario/situation/environment is definitely and certainly NOT impacted by insufficient I/O bandwidth..
However, like many people, who have the same or similar setup to myself, we experience severe delays the most basic Motion.app UI such as: selecting an item, scrubbing through the timeline, performing any kind of transform etc etc. Many of us trying to diagnose this problem (looking for any kind of diagnostics or messages etc) have noticed that with the exception of one single core, the remaining cores to do very little (idle or just barely moving) whilst the remaining single core is taking out at 100% constantly.
Many months ago whilst really bogged down with this problem trying to complete a project, I contacted Mark Spencer who politely explained that notion exploits the on-board graphics card (in my case the ATI Radeon HD 4870). After frustratingly trying to improve the performance of this and completely reinstalling Final Cut Suite in a different brand-new (at the time MacOS X 10.5.6), I found that there was little difference.
I am mentioning all this because, I know that a few colleagues have had a similar problem and have not found any satisfaction in looking at this despite many well-informed forum users who offer excellent advice.
At my wits end (currently), I took a few days to try and isolate what the problems may be caused by (what exacerbates this severely degraded performance). This user interface sludgy degradation is manifested through the UI also has the (spinning beach ball).
I isolated pieces in some of the Motion.app projects and started to ISOLATE (Control-I) what I thought were quite complex layers and individual objects but to no avail. I then resorted to completely deleting them with some improvement in performance (noticeably less sluggyness) however it still was not lightning fast as I expected considering it I was in draft mode, 720 p resolution, with lighting, shadows and reflections completely turned off in the view.
*Motion.app BEHAVIOURS*: after some hours and a great deal of trial and error (non-productive work time I might add) it occurred to me that some of the Motion.app behaviours in particular place in the layer with as few as five objects in the layer (behaviours such as "Motion.app path", "wriggle", "oscillate" and even good old trusted "throw" seem to be the culprits in this particular layer.
I will note well here at this point, but of course "camera layers" does seem to be affected at all with the basic movements such as Dolly, frame, sweep etc. I have some sets up to 4 or five cameras which seems not to bother Motion.app at all!
*OBJECT SELECTION (S):* yes this also seems to have some degrading impact on playout, scrubbing and so on. Interesting I thought.
Workarounds: here are a few things that I know that work to get around some problems of working where Motion.app is extremely SLUGGY in the user interface (UI). Perhaps someone has already noted these on a forum or posted on however I couldn't find them.
So my workflow/practice here is to do the following when I'm manipulating objects (placement, set up, applying filters, adjusting timeline, and so on):
+WORKAROUND #1+: *DISABLE the behaviours* in the layers where you are performing any object manipulation. In fact we have many objects in many layers where the topmost layer (a group of nested layers) contains any behaviours, I would suggest you disable those whilst you work on that particular layer.
It's a very simple stylus click to enable the BEHAVIOURS layers that you have been working on to see what the effect of those behaviours when you want to play them out in the player/canvas.
I have no idea why such trivial behaviours cause my very expensive Mac pro to nearly lock up whilst in Motion.app version 4 and also version 3. Anyway is definitely works on me.
+WORKAROUND #2+: *DESELECT ANY ITEM IN THE CANVAS* (in any view) when attempting to play out whilst in the canvas. Again I don't know why having one or more items (including the camera) insert would have such a drastic impact on the performance of Motion.app to play out what I think is a frivolous range, however this really works for me.
*How to measure the performance or how to monitor the performance/usage of the ATI Radeon HD 4870 graphics card from MacOS X?* I would like to know exactly what this is doing on my system when one of the CPU cores is pegged out in 100% servicing requests from Motion.app. I can't find utility (which am willing to pay for) that sees the ATI Radeon HD 4870 graphics card. One I thought would have is an application called atMonitor.app (http://www.atpurpose.com/atMonitor/) which seems to do a pretty good job on my uni body MacBook Pro and wife's Macbook Air.
It would seem that any of the utilities don't seem to see the ATI Radeon HD 4870 or if they do and they initiate commands to it that the ATI Radeon HD 4870 and doesn't respond or send any replies status information. (Beats me I'm not a technical person these days)
Summary: I would be very interested if other people who have a similar if not pretty near exact setup as myself have found these two suggestions useful. I have tried some of these Motion.app projects on my MacBook Pro uni-body and with some difference the MacBook Pro exhibits similar sluggyness to this Mac pro.

Mark, I took your advice and reinstall Final Cut Suite Version 3 (including Motion.app version 4.0.1) onto a completely different and I'm used file system including a brand-new install of MacOS X snow leopard 10.6.1, which I believe is the most recent update.
To be clear, I have all the latest Pro Applications updates as well apply to this brand-new system.
So here is the *bad new*s.
*Using exactly the same hardware configuration as I described in this theme of woe, I launched Motion.app V4 .0 .1 and opened up several of the projects that I'm having trouble with that is issued.*
Simply, the symptoms and observation I described in this thread exists with a brand-new installation.
Anyway looks like I have a backup/another instance available Final Cut Pro in case my main production image has trouble.
Once again, as I described initially in this thread, I used the two workarounds to overcome the consistent and overwhelmingly an exaggerated 20 seconds lag on average interactions with Motion.app with the success that I'd described previously.
In another thread back in September 2009, a forum poster mentioned that he felt that the camera framing behaviours were the root of this problem. And to this end he advised converting these behaviours to keyframes using the command-K ("convert to keyframes") to overcome his misery.
This indeed does work very well. So this is the third workaround and I'm starting to use.
Further I have done some more hard comparisons with my 2009 MacBook pro uni-body 2.93 GHz with a standard arrangement of 4 MB of memory and the usual disk internally. *To my great surprise*, I found that the projects that I'm having a lot of trouble with were much more responsive not only with the camera framing behaviours (which I'm not particularly having any trouble with), but the layers that contains a simple transform behaviours such as "motion path", "wiggle", and so on did not seem to bother the Mac book pro.
I watched the CPU cores on the Mac book pro maybe go to 80% while the project was loading, and also whilst I gingerly navigated through the project although feeling a little sluggy was far less in orders of 10 to 20 seconds faster than this Mac pro Nehalem with all the bells and whistles on my earnings embedded within it.
Now I'm starting to wonder, as Andy pointed out, +maybe there is some trouble with the hardware in this system+. I really could not know how to determine if this is the case. However before I draw this conclusion finally, I noticed that there are a lot more people out there with the same consideration as I have that have this same problem. It's not narrowed down to those owners with the ATI Radeon HD 4870 graphics card, however these seem to be the bulk of the people who are trying to do things that are getting a fair amount of forum time (like me).
There certainly seems to be something of an issue as there are some symptom dumps for Motion.app but only one or 2 to over this period that seemed to be triggered by something on this machine. And like many on this forum I gave up reading dumps for a living back in the 1990s.
I would really like to know how I can diagnose this problem before I had to pack this Mac pro up and carted back to the local Apple care centre here in Hong Kong (which means I won't have it forever while, which means no income). Yes I can use my Mac book pro uni-body which is I might end up doing.
_Oh, and this little gem._ I find that if I invoke the "timeline pane/window" (command-7), that it can take up to 2 seconds to refresh the screen. It is amazingly slow and feel like there is definitely something wrong.
If I have a simple motion project by that I mean some simple plates some moving text and no real 3-D except for one little camera Motion.app V 4 seems to work quite okay.
The sets that I'm working in at about eight or nine cameras over the timeline and maybe three or four sets in the project. This is not the work I think especially when most of the moving here is a few objects wobbling around in 3-D space and quick camera moves using the camera framing behaviour.
In summary, having spent what seems to be 40 or 50 hours messing with this issue are not doing anything productive, I've come to the conclusion that there is definitely something wrong with this setup that I have. However having had no problem with that up until now (I know actually I had some problems back in May 2009 with it but it seemed that install a Final Cut Suite version 2 completely fixed it.
And I am totally surprised that my Mac book pro uni-body if pressed can do the job that I want.
Therefore Motion Forum users, I really don't know what else there is to do other than to poke around over time and eventually something will fix this because it is really very frustrating and like many of us on this forum I did endeavour to pay for/put capital funds into a system highly recommended by many that uses Apple production applications than I expected it would work.
By the way, I noticed when I use Nuke version 5 and Shake V 4.1 and even Maya PE, I don't have these issues but will concede that I doubt whether the use applications take advantage directly of the GPU arrangement in the graphics card like Motion.app does.
That's all I have.
Any other thoughts are most welcome.

No Chime, display or illuminated power button QS Dual 1 Ghz

Hi. I have a PM G4 Dual 1 Ghz. It was a great computer until about 2 years ago when it sadly stopped working. I found a broken capacitor on the motherboard (No. 820-1342-B) , so figured it was a bad MB. I replaced the board with a (No. 820-1276-A) board and had no luck. The symptoms-the same as on the new board. I purchased a tested and working board (No. 820-1342-B) and still had no luck. I am beginning to suspect a problem with my processor card or my power supply but I don't want to put any more money into it. I have tried to reset PRAM but the keyboard isn't recieving power. The symptoms: Power light when pressed in, red light on logic board, fans, hd, and optical drive work. No keyboard, display, or chime. Please help- I want to donate this computer and can't bear throwing it away

You never said if you replaced the PRAM battery.
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
For G4's and earlier models, check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject.
There are other tips in there too.

Mid-2010 MacBook Pro 15" 2.8 GHz Logic Board Part Number

Hi all,
I have been searching for a few hours trying to find the part number for the logic board one of my MBPs. I, unfortunately, have the Mid-2010 15" MBP with the bad GPU that results in endless kernel panics. (I also had the first Pentium chip, the pentium 60 with the floating point error in 1995 too). I upgraded the MBP to the 2.8 GHz, core i7 (2 core) processor when I ordered it in 2010.
Anyway, the apple tech guide exploded view does not show the part number for the 2.8 GHz. It only shows the part numbers for the other 3 configurations - 2.4, 2.53 and 2.66. I took the cover and discovered my my EEE code is "QAG".
I have just started trying to figure this issue out (too much time has passed and Apple will charge me to fix). I want to try and find a replacement logic board and do it myself. Does anyone have an idea what my part number is for the logic board? None of the sites I searched have a 2.8 GHz board listed just 2.66.
An alternative question - In my PC building days, some motherboards were compatible with multiple speeds of main processors. My computer model number
MC373LL/A
is the same as the 2.66GHz model. Does the 2.66 GHz logic board support the 2.8 core i7 too? I don't want to screw up and order the wrong part.
OSX Yosemite is installed.
Thanks,
Tony

Adding RAM to 1.6 GHz G5

I just finished a rather strange process of adding RAM to my G5 which I thought I would share, in case it helps others:
First of all, I have a 1.6 GHz CPU machine, which has 4 DIMM slots. According to the Setup Guide, since there are only 4 slots (not 8), you need to use 333 MHz, PC2700 DIMMs (not 400 MHz, PC3200 DIMMs).
When I first got my G5, it came with 256 MB of RAM (2 x 128 MB 333 MHz, PC2700). About a year ago, I added 512 MB (2 x 256 MB 333 MHz, PC2700), bringing the total up to 768 MB. This addition went smoothly, without any problems.
Recently, I decided to replace the original 256 MB of RAM, with two more 256 MB modules, bringing the total up to 1.5 GB, so I ordered "1 GB DDR400 PC3200 2x512 DIMMS" (Part # M9653G/A) directly from Apple. Note that the RAM Apple currently sells is 400 MHz, PC3200, not 333 MHz, PC2700. In fact, before placing the order online, I called Apple to ask about this, and the person I talked to assured me that this would not be a problem, and that my 1.6 GHz would work with the 400 MHz, PC3200, despite what the manual says, so I ordered them.
Upon receipt, I removed the original pieces, installed the new ones, and my G5 would not acknowledge their presence. It said I only had 512 MB. I called Apple to report the problem, and they suspected it was simply faulty RAM, so they sent replacements. When I got them, I installed them, and got the same results. I called Apple to tell them it still wasn't working, and they had no idea why. Once again, I pointed out that they were sending me 400 MHz, PC3200, not 333 MHz, PC2700, and they still insisted that this was not the problem, but I started to suspect even more that it was, especially after trying to upgrade twice.
In order to test this theory, I ordered RAM from MacMall. This time I ordered 1 GB, in the form of 2 x 512 MB, 333 MHz, PC2700 (made by Kingston, Manufacturer Part No. KTA-G5333/1G). When I received these, I moved the original replacement RAM up into the top two slots, where the original ones were, and placed the two new ones in the bottom two slots. When I tried to turn the computer back on, it wouldn't. The light on the front would flash once, then pause, then flash once again, then pause, etc. When I checked the manual's troubleshooting section, it described what two, three, four, and 5 or 6 flashes meant, but not one. URGH!
At this point, I had no idea what was wrong, so I took my G5 to my local Apple store to ask them. The guy there had the idea of putting one of the original replacement RAM in one of the two top slots, and one of the new replacement RAM in the other top slot. Then he put one of the original ones in one of the two bottom slots, and one of the new ones in the other bottom slot. Believe it or not, not only did the computer turn back on, but it also recognized the new total of 1.5 GB of RAM!!!
This was such a strange process that I thought I would share it, in case someone is also currently going through this process, or wants to in the future.
Hope this helps, and I also hope I've made it clear exactly what happened. If anything isn't clear, please let me know, and I'll try again.

Power Mac G5 Mac OS X (10.4.4)

PC3200 is fine for that system. The problem was that you were installing the RAM in the wrong slots.
The RAM must be installed in matched pairs, one in the top, one in the bottom, working out from the middlemost pair.
Viewed from the side
======== Slot J14
======== Slot J12
======== Slot J11
======== Slot J13
So, one pair of identical parts goes in J11/J12, and another pair goes in J13/J14. Doesn't matter if the bigger pair is first or second.
This wasn't in the manual for your Mac?
Quad G5 2.5Ghz 4.5GB 2x250G, PB 15" 1.5Ghz,80G,1.5G Mac OS X (10.4.4)

Can a Mac Pro (2.66 ghz duel core) be upgradable to support Thunderbolt displays and other devices.

Can a Mac Pro (2.66 ghz duel core (4cores)) be upgradable to support Thunderbolt displays and other devices. Does this need to be done through the Graphics card expansion or a additional card to be inserted?

No. There is no way to upgrade any Mac Pro older then the cylindrical 2013 Mac Pro to ThunderBolt.
The requirements of Thunderbolt require a totally redesigned motherboard and chip set rather any plugin cards. These motherboard were never developed for older Mac Pros.

New Mac Pro 2.66 Ghz Nehalem Quad and FCP and Compressor

When something goes well for a change it deserves its rightful place in the posts of this discussion forum. I just completed my hook-up and an initial test on my new Nehalem quad Mac Pro, and I must say that once in a while things do work out.
1. The noise level is non-existant. I literally had to check to make sure that the unit was on. This in comparision to my G5 which sounds like the SST on take off. I might now actually hear the audio on my video monitor.
2. The speed is INCREDIBLE! Prior to shutdown, I ran a test by sending an hour's worth of mixed XDCAM EX/HDV footage to Compressor on my G5. At the highest quality 2 hour setting for DVD encoding (double pass) it took the G5 12.5 hours to encode. Running the same clip through the same version of Compressor in the Mac Pro took approximately 45 minutes. This roughly translates into a 16.5X increase in speed over my dual 2.5 Ghz processor G5. I'M SOLD! And for now, the Honeymoon continues.
The only drawback (besides the price) is that I had to buy a $100 adapter/power supply to enable my old 25" Cinema screen run on the new video card.

Mac Pro 1,1 (all Mac Pro models come with Xeon).
What matters is cleaning the X1900 of dust and from clogging intake and exhaust - every three months.
Run Apple Hardware Test from your OEM DVD.
Install SmcFanControl 2.x and keep the fans rpm to 800-900 instead of 499-599 base as minimum at least.
Monitor temperatures with Hardware Monitor or similar.
Have you been looking to see in System Profile: Memory if there are any errors?
Normally, clone backup update weekly and running Disk Warrior at the same time should be done to spot disk directory and file system problems before they get worse. Or any time your system freezes.
Freeze... and what you have 90% of the time is a corrupt directory and other errors.
At which time you may need to restore if you can't fix the problem. And don't rely on only Apple DU First Aid to find and repairs any and all errors.
For Snow Leopard maybe a flashed ATI 4870 to replace the X1900.
You may need to start over from scratch to get things stable once you find what is happening, and work with a test system until then with some trial and error. Format/initialize and clean install of 10.6.x for the OEM 10.4.7+.
At nearly 4 yrs now since it came out, not sure if you have plans for a new one.

2 vs 2.16 Ghz
