Receiving New iMac Free - Video Card Question

Much to my relief, Apple is replacing my 2008 24" iMac after I have brought it in to them 3 times for the same issue in a month (failure to startup, they have replaced two video cards, one MLB, and the display but the problem repeats itself within 1-2 weeks). They are replacing it with a newer model that has a 27" display, twice the ram (4 GB) and twice the HD space (1 TB). My question is about the video card in the new iMac, it is a ATI Radeon HD 4670 with 256 MB, and the card in my old iMac was a NVIDIA 8800 GS with 512 MB. My primary application for my iMac is gaming, which I believe makes the video card the most important component. Does anyone know the difference between 256 and 512 or anything about this new card? Should I ask them if I can pay to upgrade to the Radeon HD 4850 512 MB before I go in to pick up my new iMac?

Hi Crazy,
I had the exact same problem... my 18month old 24" iMac (with 512MB Video card) went belly up.
I pointed out that what they wanted to offer me had only the 256Mb Card ? ....and he said; "oops I didn't notice that"... so we will send your new 27" iMac - with a 512MB (ATI 4850) at no charge,
So... buddy you just need to tell them - and they will configure your replacement 27" to equal or better the minimum specification of your faulty unit.

Video card question for new iMac

Howdy all,
I'm about to order a new BTO iMac, and I'm wondering if somebody could give me feedback on the two different video cards available.
Cost is not really a concern here (I would rather spend more on the video card and cut back on something like RAM for now because RAM can be upgraded later). My main concern is performance and the best image quality.
I understand the NVidia would be faster for 3D gaming than the ATI - which I would use a little bit. So the NVidia would seem to be a no-brainer.
However, I've heard a couple people (on various forums) state that although the NVidia is definitaly faster for gaming - it performs slower than the ATI at some tasks like iMovie and iDVD tasks and text scrolling and motion are not as good.
For me, I would love to have the faster 3D gaming speed of the NVidia for the few times I do game...but the most important thing to me is image quality for things like photo and video editing, working with documents etc. Are any of these thoughts regarding the NVidia vs ATI true?
Does anybody have any advice regarding the performance these two cards? Any help would be really appreciated. Thanks!

I had the 20" 2.16 (late 2006 model) with the x1600 128MB and now have the 24" 2.8 2600Pro 256MB and 2G stock RAM. It's night and day with Call of Duty 2. I am able to play COD2 in 16:9 mode, all graphic settings max'd out and the fps? Wow! One most maps it ranges between 190-270fps! That smokes the previous version of 40-90fps. One the most complex maps my 24" drops to 90-110 range. Seriosuly, anything above about 60fps is perfectly playable! I'm thrilled with the stock card. However, COD2 is older, I play it native in OS X and do not game in boot camp. That may change a few things.

Considering a refurbished 24" Imac ... video card question?

I've been a lifelong Microhell Winblows user and am finally ready to move over to an Apple. I don't have a lot of money to drop on a Mac Pro with a separate screen so I've been thinking either a 20" or 24" iMac. Then, of course, bumping it to 4 gigs of RAM. My question is the video card. I occassionally play with Photoshop and Illustrator (for web site design). I watch DVDs and play some games.
My question is whether it is possible (or even necessary) to upgrade the 256 MB video card to a 512 in the iMac 24" (or 20") model? This is the one I am looking at now: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?nplm=FA 878LL/A
Any idea's? Issues? Things I should be concerned with? I will be adding on the 3 year AppleCare plan.
Thanks in advance for any all help you can give.

OK. One more question (if you don't mind). They are not made to be user upgradeable. I'm ok with that. Do you know if the motherboard and/or system will accept a larger video card if I have it done by an Apple technician?
Thanks again.

New GTXGe Force770 video card but Premiere pro not seeing it?

Hi - this is probably a dumb question.. but i have upgraded with a new video card which is CUDA enabled but in New Project Settings the Video render box is greyed out. What do I have to do to have Premiere & Photoshop use the maximum power of this new video card ? Am sure there is something I haven't done? is ther some driver I need to download?
HELP appreciated!

Building a new computer.. video card help?

im building a new system, planning to use after effects CS5 on it, and these are the specs.
Intel Core i7 930 2.8 GHz w/ 8mb cache
Asus P6T SE Motherboard
2 x 500GB Caviar Black 7200 RPM SATA HD (linked somehow.. raid, maybe? he said it's show up as one drive and be faster)
2 TB 5400 RPM Additional storage drive.
Patriot Extreme Performance Viper II Series DDR3 12GB (6 x 2GB)
GeForce GTS 250 512MB PCI-E w/ DVI, HDMI
and a 24" Samsung Display.
This has run me 2200, already a little over over my budget?
My question is, is it worth the upgrade to a 285 (or maybe a Quadro)? This'll cost probably 300-400 more dollars. How different will it really be with this Mercury Playback Engine?

If you build the PC and it has RAID you can use a RAID 0 (striping). It
reads and writes faster but if one drive fails all is lost as each drive only contains half of
the data. I run an ICor7 920 2.66 that boots from a Western Digital 10K hard drive and runs two 500 GB drives in a RAID 0 for data drive. I didn't get the boost I expected from the RAID 0. I run two monitors with a 512 MB NVidia 8400 video card running my editing screen and a 1 GB NVidia 9500 running my display monitor. It works pretty well. The CS5 x64 really made it better but if I have too many layered sequences I have to reduce the monitoring to 1/4 res. I run Windows7 x64.

My 4yr old iMac's video card caught fire, should apple replace it?

I bought an iMac on Monday 24th December 2007, and after attempting to turn it on - 19th January 2012 the video card caught fire in it and has damaged the computer completely.
I find this very surprising from such a high quality brand such as Apple, and I'm wondering if I'm within my rights as a consumer to ask for a refund or fully paid repair. The computer is barely four years old and I treat it with kid gloves. I keep it well away from any danger and it sits comfortably on a solid wood desk, So again I find it impossible to believe that this is a 'natural death' of a iMac.
I took the iMac to a reputable apple centre who quoted me around £1200 to repair the faulty machine.
Cana anyone offer any advice or have suffered any similar problems?

Your iMac is far beyond it's normal warranty, and even beyond the period that would be covered by AppleCare. So getting Apple to cover the issue for free is highly unlikely. I doubt that any consumer rights group would find that Apple is obligated in this matter.
You can of course call Apple support and discuss the matter with them, but even if the iMac actually caught fire rather than a chip just failing (which can in some cases result in significant smoke and stink and make it seem like there was a fire), it's not likely Apple will do anything for you since you probably could not prove that the fire wasn't caused by dust or other debris in the system.
Regards.

Buying new iMac, which graphics card would be best?

I'm getting ready to buy a new iMac. I already have a 2010 27-in with a Radeon HD 5670 512 MB graphics (card? was built in as I remember). I need an additional iMac for my studio space and am deciding between the 21.5-in. w/ Intel Iris Integrated graphics and the NVIDIA GEForce graphics models. I do photography and art related video projects with music (Final Cut, Photoshop CSS, Logic Pro).
The 2010 iMac has worked fine for me. Which of the new iMacs would you recommend? Do I need extra dedicated graphics card or is the Intel Iris pretty comparable to what I've been getting with the Radeon?
I wouldn't mind saving a couple of hundred dollars to use on other things like a back up drive, but if it's going to be a big difference I could spend the extra $ for the NVIDIA.
I'm not a gamer BTW.
thanks for your input, tech-heads!

Although the processor speed is slower, the i5 is much more efficient
than the i3. In addition, the memory bus speed is faster than your
2010. The result is you will have a faster computer.
Just for some performance numbers, here are the Geekbench
scores for your current computer and the one you are considering.
(64 bit single core test score/64 bit multi core test score)
2010, i3, 3.2 GHz iMac ---> 2086/4491

New imac 21, airport card anomalies...

hello everybody
just to inform, as here apple ssupport didn't ptopose such "simple`" solution to a kind of network misconfiguration , bad access to web services, aso
1) after a few s=days, a brand new imac 2.5 g intel core i5 was not connecting to te router correctly.
2) when calling apple support, describing the airport icon showing @no airport card connected@,(even if the system info[locations showed a card and even the modem data on screen..) so i had to pack tje machine and travel to such apple center downtown, Polanco, and here in Mexico it's a real pleasure to ride some 2 hours in eavy traffic..
3) arriving there, no airport card problem, and the technician described me a probable motherboard saturation or even overheating situation, i said ok, will go home and see if everything keeps working fine.
4) a few days later, again, no access to web, automatic or personalized network or account adjustments seem fine.. but no way to receive or send mail, web pages crazyly slow, aso...
5) when 24 hours later no way to see nothing, even the airport icon with stripes shows just clear empty grayish icon..
6) calling again ther apple service center, again they ask me to carry the stuff downtown, must be or could be probably a configuration problem, need to be checked there, aso, no way to look for or propose some solution just by calling them aso.
7) calling ip service, we tried for more than an hour to check , trying all options, f.i. using ethernet cable (modem always good, and machine working fine then) we examined all options, accounts configuration, the automatic was not accepting a connection, system showing "Airport connected but no ip address because not attributed, or missing", aso)
8) and when changing from automatic locatoon to the configuration we had installed weeks before to help solve the connection problem , same result.
the directions of ip, router subnet mask aso were correct, changed eventually, no way, nothing was connecting., we tried quitiing such non automatic configuration to avoid possible conflicts, no results.
9) after an hour or so, the technician from my IP offered to quit the airport configuration (even with a green bulb visible that airport config was not connecting, the desktop icon was sometimes greyish, sometimes empty, aso...) and add a new one.
10) at the moment it was created (as "airport 2") ... the automatic configuration looked instantly for another ip adress, and everything works fine now..
SOSO why doesn[t apple support technicians have suchj ideas ? why did the airport icon even show a "not connected{ airport card message ?
I phoned those apple guys around, explained them the solution offerde by phone by the IOP provider, no comment, answer or even a simpe "thanks" for such suggestion , from them, whan the received such info, Hopefully will eb useful for others users, and eventually after a post here. tschuss
Form Mexico city...

Looks like this issue has hit its fair share of people. Spoke to Apple support today about the same issue. Brand new iMac 27' 2.8 quad core with 8gb of ram and I opened the box only to find my airport card was not recognized by OSX. After performing several support steps, the staff let me know that this was indeed a hardware related issue - I am not advocating this is everyone'e issue just mine.
Here is what we did to troubleshoot and determine it was hardware related.
Open system profiler / go to network and look at airport - if all you see is "software versions" your hardware is not recognized. You will need to reboot the system and clear the SMC. To do this do the following:
Unplug everything from your iMac and wait 60 seconds with absolutely nothing connected to it. After that, plug in your power cable and press the power button down, letting it go after 2 seconds. Immediately after the power button is let go - hold down option + apple + p + r you will hear 2 "bong" sounds, then let go of the keys and boot. If your hardware does not show up you will need to boot to the OSX install DVD to get a "clean" install of OSX.
Boot to OSX DVD
Insert DVD
Shut down system
Power on system - hold down C key until you hear a chime then let go. System will boot to OSX install.
Once you pass all the prompts by selecting defaults, you will come to "Install MAC OSX" asking you to select the disk where you want to install. DO NOT CLICK INSTALL. Open Utilities / System profiler. If you still do not see anything under Airport other than software, your Airport card is bad or at the very least not showing up in the OS. If you do see the airport card there, you will need to reinstall the OS to have it recognize the card.
Hope that helps!

IMac Display/Video card "error"

Hey ppl, just had the most random thing happen to my new iMac Core Duo 20" today. ive had it for under a month, and its the standard model from Apple. I had a few Apps open, and was using VLC to play a video file.... suddenly, the entire display goes washed out(very bright white/yellow) with a few colored bands going from top to bottom. I could hear the audio from the video playing...but i couldnt make the display get back to normal (force quit, etc). So i had to do a manual reboot of the system and all was fine.
Anyoneelse here experience anything like this ? or anyone here know why something like this would happen ?
Cheers

this could be caused by any number of things. i would reset the pram holding apple-option-p-r and that might help. but i would also run the apple hardware test. you can do that by booting to your install disk holding the d key. could be the logic board. but could also be inverter, or video card. it could even be software related. i would definitely run apple hardware test though and see if everything checks out. [ 8 ) ]

Can my Late 2009 24" iMac's video card be replaced without replacing the entire logic board?

Can someone help me determine if my video card is built onto the logic board on my Late 2009 Intel 3.06 mhz 24" iMac? The video shows corruption (checkered blocks) with a progress bar at the bottom of the screen, then it reboots in a cycle.
According to similar problems found on the web, I'm failry sure that the VRAM is corrupt. Apple Tech support had me do a reset on the PRAM and that only changed the direction of the corrupt pixels on my display. I also ran the Apple hardware diagnostic program that came with the iMac 3 times and it found no problems (from what I could tell squinting through my corrupt display). The S/N is W891507C250.
Thank you,
Will W.

I appreciate your reply and you are correct about it being an Early 2009 iMac.
But I'm not sure that you are correct that all Early 2009 iMac's do not have seperate video cards though. You may be, but according to other sources on the net (such as the link below) claim that some Early 2009 24" iMac models with certain video cards (i.e. NVidia, which I have in mine) are replaceable without replacing the entire logic board.
Again your feedback is appreciated, but I was kind of hoping for an Apple employee or at least an Apple Support Forum Admin to give me an official answer.

New MACpro Configuration - Video Cards

hello,
i am trying to configure my macPro online, my question is about the VideoCards, is it better to have 4x the Nvidia Card on the ATI with 512 MB??
I am mainly using Apeture, After effects,Motion and PS.
What should i do?
Thank you

the only main reason to have more than 1 video card is if you need to hook up more than 2 monitors.
there is a minority of users that know how to and can utilize two of the 7300 in SLI while running Windows in Bootcamp, but the performance of the SLI'd 7300 is much much less than the single ATI X1900.
the X1900 is much more powerful than the 7300, so if you are going to do a lot of work in Apeture and Motion, and you aren't going to use 3 or more monitors, then the right choice for you is the ATI X1900 hands down.
If you were only the occassional Aperture / Motion user, then you would not see a day to day difference between the 7300 and the X1900, as the faster card really only shows its muscle with certain tasks, it does not help while performing more mundane duties.

Purchasing new iMac 04/22/09 Questions

I want to purchase an iMac 24” this weekend but I am concerned about the issues with the video cards freezing the computer. Should I not buy one at all or purchase one with the NVIDIA GeForce 130 512MB vs the ATI Redeon HD 4850 512 MB. Is this a bug or hardware issue?
If you can help me with an honest answer I would really appreciate it.

In that case I would recommend getting the base 24" iMac either the 2.66 or 2.93 machines. Your needs aren't graphics intensive so you would not see any improvements by upgrading the graphics card. Another option... Apple is selling the previous generation 2.8 machines with a very good discount, go to Apple.com, Store, Clearance and you will see it. For your needs this would be a great alternative. I don't know if retail stores have these in stock, if not you would need to purchase directly from Apple online. For your music and movies I would store these on an external drive rather than using up precious space on your internal drive. External drives are inexpensive and provide more flexibility.

Photoshop CS6 / Video Cards Question

I am purchasing a new computer and was wondering if anyone had any opinions on whether nVidia or AMD would be better for use with Photoshop CS6. In my previous computers, I've only ever had an integrated video card and they worked okay enough with Photoshop. But now I have the opportunity to purchase a computer with an nVidia/2 Gig Vram or an AMD Radeon/1 gig VRAM video card.
This is very generalized since I know so much depends on the cpu speed, ram, whether or not you have multiple hard drives, etcetera.
I've got a clear idea of what I want for all the other components of the computer, but I have no working knowledge of video cards.
I use Photoshop for photo editing and I also want to eventually use it for High Definition Photography editing.
FYI, I don't do any gaming.
Thanks for any opinions and help!!

I usually recommend ATI over nVidia, just because over the past few years as an OpenGL software developer myself I've seen better driver quality from AMD (ATI), but I don't know that past experience is an indication of current performance... Right now today ATI driver quality has slipped a little, while nVidia's has gotten better.
That said, my most recent purchase was a VisionTek ATI Radeon HD 7850 card. A 7750, at about half the price, probably would have done fine, but I figure the 2 GB onboard RAM makes the 7850 a bit more future-proof.
Something important to think about when choosing a video card is this: Watch how much electrical power they need. Video cards, because they have very fast processors, tend to require a lot of wattage and make a lot of heat, and many computers simply don't have the capacity to provide an extra hundred watts of power to a video card, nor exhaust the heat very well, so adding a power-hungry card could destabilize your system or cause heat problems. Something like the Radeon 7750 has a very low power draw. NVidia has some low power models as well, no doubt, but I'm not as familiar with the models.
Photoshop loves working with a video card that scores 1000 or higher on this chart:
