Does 4 x ATI Radeon HD 2600 XT 256MB translate into 4 x performance?

I have never been into pc gaming, but I recently got a new mac pro (8 core 2.8 ghz, 8 gb ram, 4x ati radeon hd 2600 xt) and was wondering if these graphics cards (which I got for the multiple monitor functionallity) would perform in unison, making them more or less equivalent to a 4x better graphics card for gaming, or if they are only good for multiple monitors.
If they are not good for gaming, any input as to solutions that have worked for you (two 8800's perhaps?) in that area would be appreciated.
Thanks in advance,
Jarrodsl

ATI, and nVidia both have multi-card interface schemes available - ATI's being called crossfire, and nVidia's being called SLI. Niether, are supported under mac osx. e
Bay one of your ATI cards, and replace it with an nVidia 8800 GT (in the first slot), that card performs very well for gaming, it ranks high on tom's hardware vga charts.

I have an 20 inch Imac 2,4 GHz Intel Core 2 Duo and I want to introduce Final Cut Pro X into the machine, can I change the Vieodcard ATI Radeon HD 2600 Pro 256 MB, into a more suitable videocard? Or is that not possible?

I have an 20 inch Imac 2,4 GHz Intel Core 2 Duo and I want to introduce Final Cut Pro X into the machine. Can I change the present Videocard ATI Radeon HD 2600 Pro 256 MB, into a more suitable videocard? Or is that not possible? I have upgraded the memory to 4 GB 667 MHz DDR2 SDRAM.

The GPU in a iMac is NOT upgradeable.
You should check to see if your model of iMac meets the minimum specs to run FCPX.
I believe that your GPU is NOT OpenCL capable, and hence not supported.
Even if it works, you would probably get marginal performance.
What you can do is download the trial version and see how (and if) it works.

IMovie 10 on an iMac 24-inch Mid 2007 with ATI Radeon HD 2600 Pro 256MB?

Will iMovie 10 ever be installable on an iMac 24-inch Mid 2007 with ATI Radeon HD 2600 Pro 256MB?

They updated iMovie to 10.0.1 so it will work with these Mavericks machines:
http://support.apple.com/kb/HT6023
"Installing iMovie (2013) previously required a computer with an OpenCL-capable video card. This requirement was removed, and you can install iMovie version 10.0.1 on any Mac with OS X Mavericks."

Best option for replacing a faulty ATI Radeon x 2600 XT 256mb

My graphics card has just packed up, and I am struggling to find anybody at the Apple Technical Support service to give me a straight answer.
I am not a gamer, and only require a card that will allow me day today use and for general camcorder editing (novice level).
I had an ATI Radeon HD 2600 XT - standard install. in my MacPro (early 2008) 2.8Ghz, Dual Quad Intel chipset, OSX 10.6 (snow leopard).
Can anyone recommend the best option for ATI card, as I have read theyh perform better than the Nvidia cards.

I'd get ATI HD Radeon 4870 Mac Edition from Apple.
The GT is more like spare or for 3 monitors. Why or how Nvidia got that card to be adopted as the OEM standard in a workstation, and not say GTS/GTX 200 series is, beyond me. One year ATI, next year Nvidia gets the "prize" seems to be the order of the day.
Nvidia drivers have been a problem for Apple for years, the GTX 285 would do some serious damage to 3D and CS4/5. Two dual width card design the way a Quadro CX handles CS4 for Windows to do realtime image rendering instantly.
I wouldn't flash unless you like to dabble or want to learn. In which case a 1GB card would make more sense.
Surprised though the manager didn't steer you toward the 4870.

IMovie 10.0 Oct 22, 2013 won't install on my Mac Pro 2008 with OS X 10.9. Software Updater says "Your computer's video card does not meet the minimum system requirements". I have ATI Radeon HD 2600 XT 256 MB. What card SHOULD I have?

After installing Mavericks on my 2008 Mac Pro (10GBRAM, several HDs, 2 x 2.8 GHz Quad-Core Intel Xeon) Software updater says there is an update available. iMovie Apple Version 10.0 Released Oct 22, 2013.
So I click the UPDATE button
Software Updater puts up a dialog that says "Your computer’s video card does not meet the minimum system requirements".
I have ATI Radeon HD 2600 XT 256 MB. What card SHOULD I have?
Thanks.

It is a easy fix to this problem.
I have this video card
iMac 24 inch, early 2008.
Graphics card: ATI Radeon HD 2600 Pro 256 MB .
This is what you do.
1. open app store.
2.go to the update tab.
Yuo will see the imovie icon waiting to install.
3.clic the sub menu tab and select "try apdate in an hour" option from the sub menu.
4.leave the app store window open and came back in an 1hr .
Like magic you will see the imovie app being upgrade it in the lunch pad .
enjoy it.

I have installed FCPX on my iMac (mid 2007) with a video ATI Radeon HD 2600 Pro 256 MB. Tis does not meet the minimum requirements. It seems to be ok but what kind of problems can I expect ?

Hey Luis. I not only remember…I still have mine (OS 9)! Works perfectly well…for some things; just need to be selective about what I ask it to do. (Also have its big brother Pismo running Tiger, which is still an extremely competent machine.) When I take them out of their cases, I'm still amazed at the G3's build quality.

Hi thanks for responding.
I downloaded the 30 day trial version and it will not let me open FCP X. Everytime I attempt to open the trial version I get a message that says,
"This system does not meet the minimum system requirements for graphics cards. For more information on minimum system requirements, visit the Tech Specs page on the Final Cut Pro website."
When I look at the specs for FCP X, I don't see the ATI Radeon 2600 as a graphics card that can be used by FCP X. That's why I'm looking to upgrade, at least my graphics card for starters.

ATI Radeon HD 2600 XT - HDMI signal loss to LCD TV

I have a new Mac Pro 2008 with ATI Radeon HD 2600 XT connected to a Sharp LC-42D64U 1080p TV via a DVI to HDMI cable. If I turn the TV off or change the input from the computer to TV and back I get an error message that an incompatible signal is being sent from the output device. Unplugging and plugging cable back in does not reset. I have to hard power off the computer for the signal to be corrected. The Sharp is the only "monitor" connected and nothing else is connected to it.

Thanks for suggestion.
So it must be a real problem, if a company decided to build a device to sell that could take care of it.
What a joke, I am pretty sure this problem is due to the junk ATI card in the machine. There isn't even a support listing on ATI for the card (with mac). However when you search for the problem it was prevalent in a lot of the cards going back to 2005. All of the support responses were the next round of drivers will fix it.

Where can I find 24" ATI RADEON HD 4850 video card or if there is one compereble to it or dose Aple replaces with new one, because ATI RADEON HD 2600 is deffective and APPLE dose free replacment. Thanks

Second ATI Radeon HD 2600 XT Won't install

I purchased a second ATI Radeon HD 2600 XT video card from VisionTek (the same card pre installed in my early 2008 mac pro) so as to run a third monitor. I assumed because the drivers are already loaded and i knew that the card was compatible that it would be an easy plug and play situation.
However, when i popped the card in and turned on my mac, i got the grey screens of death (from the first and original card) and then a crash notice (where the screen dims and it tells you to manually turn off the computer).
i installed the new card in the first slot to see if it would even register, and it did not.
some specifics: the new card is slightly different in design, physically. the fan is slightly larger (though it doesnt appear to physically be touching anything, it certainly doesnt appear to be too big for the machine), and when i install it into the PCIe slot, it does seem to slide in ok but stops not even 1/8 of an inch from clicking in. i can put the 2-screwed retainer bar on but with just the slightest force. it doesnt appear to be fully seated, but it seems like the connection should be sufficient.
any help would be massivly appreciated. the card should work right? i've definitley confirmed that it is compatible, is it simply a physical problem with the card?
thanks in advance for any insight or advice.
alternatively, can anyone suggest if this is something worth spending $40 on a non apple care apple support call? or a trip to the apple store with (ugh) computer in tow?
thanks!

Whatever you purchased, likely it does not have Apple ROM.

Better chance of find something that works. Apple only has ATI 5x70 ($249-449)

Adding a ATI Radeon HD 2600 XT 512. Is it compatable?

I will be purchasing a Mac Pro soon. As you all know it comes with the ATI Radeon HD 2600 XT w/256mb. Being that I am a PC user I have in my possession a Dell gift card. Now, at the Dell online store I am able to purchase another ATI Radeon HD 2600 XT for less than half of adding a second card at the time of purchase, but this one comes with 512mb. I'm not 100% sure but by comparing images at Mac and ATI, I think the two cards are manufactured by the same company which is VisionTek. Does any body know if these two cards will work together or even if the 512 will work at all?I have researched ATI and they don't even aknowledge the 2600 as a Mac compatable card. I have tried calling Mac, they said come here.

The Dell card will not work with OSX. How many displays do you have? Extra graphics cards are only useful if you have more than two displays. They will not make things run faster.

ATI Radeon HD 2600 XT and early Mac Pro

I have been following the debate regarding the ATI Radeon HD 2600 XT and old Mac Pro with interest, however my problem is not quite the same. As all the correspondents are located in the USA. I would guess they are referring to Apple part no MB198Z/A. But ATI Radeon HD 2600 XT is sold in the UK by Apple as part no MB198, and I cannot be sure that it has an identical spec. Does one Know the Answer? Please respond if you know
Thank You
For info Below is the response given by ATI
(The specifications are the same. The HD 2000 series cards runs on PCIE 1.1. You will need to confirm this with www.apple.com since the cards are specifically flashed by Apple. These cards may contain different video bios versions.)

M.O.K.,
Based on the ATI information regarding PCIE 1.1, the card is the same and should work. I would call Apple when ordering to confirm.
I have the 2600 XT in my 2.66Ghz Mac Pro and it works very well. Much better than the OEM card.

Problems with ATI Radeon HD 2600, electrical interference or flickering pix

Problems with ATI Radeon HD 2600, electrical interference or flickering pixels
I have a Macro 8 core purchased just 4 months ago with the ATI Radeon HD 2600. Just started getting what looks like electrical interference or flickering pixels all over the screen. It gets worse and worse to the point where i see and cant work then clears up for an hour and then comes back.
If I change the resolution from 1680x1050 to 1600x1200 everything looks fine and the problem goes away.
Monitor works fine on two other computers, driver is up to date.
Would like to upgrade at some point just disappointed that I’m already having problems.
Any suggestions would be very helpful, in the mean time I’ll searching the forums.
Thanks,

When you called Applecare or went to a Genius bar were they of no help?

Multiple ATI Radeon HD 2600 XT cards in a Mac Pro

I'm wondering if anyone has any experience with screen spanning with multiple ATI Radeon HD 2600 XT cards. What I'm looking to do is super widescreen presentations with keynote and I need more pixels. Right now I use the Matrox Dual and Triple head to go GXMs to achieve this because they make the computer see multiple monitors as one giant display but I am limited to 3840x1200 (dual 1920x1200) I was wondering if multiple video cards would also see the displays as one giant desktop?
It works on a PC but then I have to use PowerPoint (ugh). Any help or suggestions with this? Thanks in advance.

Multiple graphics cards will make the displays act as one large desktop, but when an application is set to full screen mode, it usually will just use one display. If the application is run in window mode, you should be able to move and enlarge (by dragging the lower-right corner) the window to use all displays, but there will be a window border (and menu bar on one display). You could zoom the display slightly to move the border off-screen. There is a setting in Zoom Options of "Universal Access" system preference to stop the zoomed image from moving unless the pointer reaches an edge.

Resetting a video card? (ATI Radeon HD 2600 XT)

So here's my issue. I am trying to connect a secondary monitor to my mac pro (10.5.8). The card in the machine is a ATI Radeon HD 2600 XT. The only port that seems to work on the card is "#2" (or the left port while looking at the card from the back of the machine).
Both monitors work when plugged into #2 so I know the problem is not with the monitors/cables. This leads me to believe the card has some issues. I used a secondary screen on this machine about a month ago and had no problems. Not to say the card isn't bad, but is there any way to reset this card or flush out some sort of cash/preference to see if that works?
I have done the obvious "Detect Displays", and have flushed the PRAM of the machine, I've tried booting it up with no screens, just one screen, etc. I've tried booting with one screen hooked up to port #1 and it never get any signal so I'm thinking it's a dead port unless I can somehow "refresh" this. System Profiler just shows whichever screen is connected to port #2 and "No display connected" for whatever is in port #1
Any ideas? I've done just about everything I can think of. I tried installing the firmware update too for the card, but on trying to do so it said that I couldn't because I was already running the latest firmware.

ok walter, we gonna help you no problem. maybe try shutting down your mac pro and
using some compressed air and clean that out, especially the ATI Radeon 2600. Dust bunnies love the video cards. then restart, open up disk utility and repair permissions
if you can. If not, then yes, your video card is probably dying. Go to the Apple at the corner of your screen and click on "About this Mac" and it should tell you what kind of Mac Pro you have. As far as I know the ATI 5770 would be a good replacement for your ATI 2600. Apparently they were known to collect dust pretty easily, or so I was told. do you have Applecare? otherwise, I think it's gonna be around $300. Luckily installation isn't too hard. Oh, and you're probably going to need to have 10.6 already installed on your Mac Pro, I think
well, enough
