IMac graphics cards

I just received my iMac and I love it! With that said, I was curious if there are more advanced graphics cards to which I can upgrade. Yes, yes, I know ... Macs and gaming don't necessarily go hand-in-hand ... but does ATI have a higher-end card that will work with the iMac besides the HD2600 Pro that it comes with?
Thanks in advance for taking the time to answer.

Hello,
The imac graphics card can't be upgraded and HD2600 Pro is best available right now for iMac.
I tryed to play lots of games on my iMac and all seems ok. In World of Warcraft, if i put multisapling at 4x or more the framerate drops down but at 1x an 2x at 1680x1050 the game run at about 60 fps that i think is not so bad...
Well... is all about tunning the settings.

Upgrading your iMac Graphic Card??

Hello,
I have been looking around for an answer with no hope to find one for my question!!
Why I can't update my iMac Graphic Card to something better? Why this option was not given?
A big company like Apple should have a solution to this issue, you have to....
Any thoughts!!

Please tell us the year/specifications of your iMac so we can determine whether it is worth/compatible with an upgrade.
While it is more than possible to upgrade an iMac's GPU, (people say its soldered to the mb, trust me its not as I have taken mine apart for myself).
However most iMac users will never perform an upgrade such as this for 2 reasons:
1: The mere process of scouring the web for a specially flashed Mobile MX A/B sized card suitable for installation.
2: The cost, it is expensive and will most likely be more than half the price of the original cost of the unit.
However if you really want to tinker with it, i would take a look over iFixit teardowns/guides to see if you feel comfortable enough dealing with the insides of your machine.
I personally will be saving money for a better speced computer, rather than forking out a fortune for a minor GPU upgrade, and depending on your budget/age of your machine you should probably too.
Thats just the way it is! Sorry

IMac 24' green & magenta vertical Lines will not boot.

Firstly let me say Hello all ^_^ Secondly, I hope this is posted in the right forum. :Oops:
The problem started a few days ago when my iMac went into screen saver mode and the whole screen had frozen and become pixlated with squares and a general scrambling of the screen, noise, grain, etc.. It wouldn't awaken from it's slumber so I did a hard restart.
The familiar friendly chime greeted me but the screen was covered in Vertical Green lines that are full of pixels, moving almost like static. The apple logo appeared and the spinning gear but that stopped spinning after about 20 - 30 seconds.
When I tried to boot into Safe mode this happened to the Apple logo (after about 3 or 4 mins)
The apple genius' are booked solid till next Thursday (27th) so I decided research and trial an error were my best options.
The following are the steps I have tried and where I am currently. Sorry for the lack of punctuation, etc...
On startup, Chime sounds, green vertical lines with what appears to be static, sometimes with Magenta in.
Apple logo appears
spinning lines lock up after about 10 seconds. Freeze.
Will not boot into Safe mode (by holding Shift after chime)
Will not boot from Mac OSX disk (by holding C after Chime)
Tried zapping the Pram (Shift, option, p & r on chime, Wait for 3 chimes)
Removed RAM 1 at a time tested in other slots, no change.
WILL enter into single user mode (holding Shift & S after Chime) so ran fsck twice to receive the Hard drive OK message. PHew Hard drive is OK then.
Reboot from here, same Vertical Magenta and green (sometimes just Green) Lines with static, Apple Logo, Spinning gear and freeze.
So connected with firewire into target disk mode. (connect mac book pro to imac using firewire cable and hold down the T key on your target computer, in my case my iMac) This essentially makes the imacs hard drive into an external firewire drive. Hard drive OK. Backed up. YAY. (most relieved to get back photos & current work)
Thanks for bearing with me on this epic post. ;);) and thanks in advance for sharing the knowledge.

Maybe this is a little late since this was last year but I thought I would post what the actual problem & solution was.
I took the iMac into see the Genius' and as it turns out it is indeed the graphics card. Luckily enough for me my iMac was just before they started soldering on them onto the logic boards AND it's one of the known faulty Nvidia Cards, which means a free repair, (luckily)
It took about 2 weeks to repair. when I recieved my iMac back unfortunatly there was lots of fingerprints inside the screen. Let it be said that the Mac store in Oxford street are the fairest of all, as instead of taking the machine and re-repairing, they replaced the whole iMac for a new one.
I hope anyone with this problem, or any other, has the same level of care from Mac as I have had.

Imac startup issues- green vertical lines changing to grey screen

Help! I think my 27" i7 iMac just died!
Yesterday morning, I had a kernal panic while using Safari. Restarted, ran disk utility twice. A bunch of "library shoyuld be r- instead of -rw" type errors that could not be repaired were found both times.
After second round of computer restart/disk utility, the computer started displaying green lines running vertically down the grey screen.
After around a minute and a half, the screen became grey only, no green lines- no apple logo.
I attempted to restart holding down the shift key, I saw the startup/repair process "kick in" (the horizontal repair bar running across the bottom of the screen).
Once that was finished, I got about a minute and a half worth of "spinning cursor" and then a pretty blue-lined screen (of death)
(NOTE--bright white lights are flash from camera- not on screen)
I cannot access anything now. I know that I am running whatever the current version of OS 10.8X is now.
I am stuck- anybody got any ideas?

I have to have my serial number to give them to start the call. I have no way to access the serial number on the computer because I cannot advance past the grey/blue screen to access it. Is there a way to get the serial number on this computer off of the hardware itself?
Look on the bottom of the stand, Apple used to print them there I don't know if they still do or not. Also if you have the original box it's printed on that too.
In addition if you click about this Mac and click the version of OS X installed a couple of times the serial number will appear. In addition you can run System Information and get the serial number there too.
Finally it's not going to do much good to call Apple, you need to take the machine in for repair at your local Apple Store or AASP. I suspect your graphics card has failed.

Intel iMac (Early 2008) Has vertical lines on the screen and doesn't boot.

My iMac froze up tonight, and upon restarting it there are a number of yellow vertical line segments throughout the display, and it will not boot completely into the OS. The spinning segment just stops and the computer does nothing. I inserted my Leopard disc to run a hardware test but holding D during bootup does nothing, even though I can hear the disc spin up.

Any Thoughts?

I've had this same exact issue and have had to have the graphics card replace (nvidia 8800gs).
It seems these graphics cards are defective in some way.
Unfortunately my iMac is out of warranty and I must pay 3500dkk ( 500usd ) for repair.
I'm very disappointed as to the reliability of these iMacs as I've only had it for 2 years my old iMac g4 1ghz has performed better than this and is actually what I'm using until my so called new iMac is back from repairs

Mid 2011 imac graphics card

Sometimes getting green vertical lines at start up and then will not boot up. Restart a few times and then it finally functions properly for a while. Not sure if there is a user friendly fix or not.
Thanks

The iMac's GPU is damaged. GPU problems appear and disappear, so it's normal that sometimes the iMac works correctly.
Now, I recommend you to take the iMac to an Apple Store or reseller to get your GPU replaced. The GPU isn't expensive (about $99, depending on the GPU), so it's better to take it instead of trying to do it yourself. I haven't found the steps to replace the GPU on the Mid 2011 iMac

27" iMac graphics card, do I need the upgrade?

I'm intending to purchase my first iMac, which I hope to use for recording and editing video gameplay via a PS3, and in some cases games played on the iMac as well. Most games I'll be playing aren't going to be triple-A games, so I'm not sure if I need to invest in the more powerful graphics card (about 70% of the games will be via PS3 anyway), so is the additional cost really worth it? Same question goes for the processor, I was planning to upgrade to the 3.4 GHz i7, but is this really going to pay off over the course of my computer's lifespan?

I can't quite buy into throwing down the extra $140.
Depends on the App & the future, but how may hours a year doing video editing would it take to amortize $140?
Not the iMac model, but...

IMac, graphics card and Final Cut Studio

I have an iMac, Intel Core Duo 1.83G, 1 GB 667MHz RAM. I finally made the plunge and bought and tried installing FCStudio 2 but it wants a different graphics card. Can my CPU support FCP and if so, what graphics card is recommended and what sort of RAM do I really need to run this well? Or am I better off getting a different computer? Thanks for your advice

... what graphics card is recommended ...
AFAIK you cannot upgrade your graphic card in any iMac. Did you check the system requirements for FCS?

IMac graphics card going nuts

We use Archicad as a CAD program to a high level on our 20" intel based iMac's. when in the 3D window of archicad for a period of time, our graphics cards are, to put it technically, crapping out.
we loose all visual graphics content, however all menus and alike work. We get yellow triangles all over the screen.
If this works, see the imbedded screen shots I took on my last escapade.
the only way to fix each time is to log out and log back into the computer.

The links appear to point at your local disc (Hard Drive) and consequently don't work. At least not from my point of view they don't.

IMac graphics card

Is it possible to upgrade the graphics card in any mac? I've had a couple of apple people tell me this isn't possible. But come on!!! How can they possibly not allow you to upgrade a graphics card?
Does anyone know if this is possible if it is taken apart and a new one is put in? Yes I know it would void the warranty if it was still under warranty, I'm just curious. Because when it's not under warranty anymore, I very well may try to upgrade the graphics card. I have a Nividia 256MB graphics cards.
I've had some family tell me I would NEVER need a 512MB graphics card, but then some friends of mine that are gamers tell me they had like a 700MB graphics card and are about to upgrade to a 1GB graphics card.
any ideas on this? WoW looks pretty good on my 256MB graphics card, I just don't know if I'd ever run into any problems.

ok awesome, thanks for all the info. anyone know why this other guy said I could? haha...oh well not important.
so the mac pro is upgradeable?!? sweet! I've always liked the idea of having no tower and having everything built in. Then again, if the mac pro is as upgradeable as a PC, that would be awesome...would anyone consider it just as upgradeable as a PC? ex. HD, graphics card, processor, etc.
If you wanted a higher-performing graphics, why didn't you buy the iMac with the upgraded graphics option? Have you tried any specific games that don't perform well on the iMac? Or are you just listening to your PC friends that claim you need a 1GB graphics card just so you can sound cool? Most are overkill and not needed. If you are happy with how the game performs, then you don't need a new graphics card.
The Mac Pro is a standard tower computer. One that is quite large and quite heavy. Yes, you can replace or add graphics cards because they have expansion slots. You can replace the HD in both the iMac and Mac Pro. The Mac Pro has room for additional hard drives, the iMac does not. The CPU is socketed in the Mac Pro, but there aren't any processors available that exceed what is already installed. Some people have upgraded the CPU in their 2006 Mac Pros, only because the 2008 Mac Pro offers a newer CPU. Be ready to drop $2,500 for the Mac Pro, without a monitor.
I prefer the iMac since it is very fast with the Intel Core 2 Duo CPU. I don't want a large tower taking up space and adding additional noise to the room.

IMac graphics card availability?

I have an iMac circa 2008 and am told it needs a replacement graphics card. However it appears that a low spec cheaper card is not available and I need to replace with more expensive higher spec card. The price difference is well over £100 pounds. I'm not sure I need the high spec card and I can't really afford it. Is the computer still worth the investment and why are there no cheaper low spec cards available .

You cannot replace the GPU in those models if they are soldered to the board. If the GPU is socketed you cannot use another GPU because the rest of the hardware would lack the design to support it. Plus you could only use a chip that also used the same socket configuration.

New iMac Graphic Cards

Yes I am a multimeida major in college and I am thinking of buying the new iMac I have an older G4 Powerbook that works ok but it will not run the new iMoive. So I am thinking in time the G4's will be a thing of the past. My question is, I don't play much games at all but if I did get into playing games is the iMac good for games or no? I mean i've heard the graphics card is not that great but I don't know much about graphic cards. Any help would be great.
Tony

We just bought a new aluminum 20 inch iMac. The only game my family plays is the Sims 2. Imagine our shock at discovering that our sparkly new computer won't play this game. Aspyr (the company that makes the Sims 2 for Mac) tells me that at this time they cannot support any of their games on the new iMacs because of the ATI 2400/2600. They are working with Apple to try and fix the problem, but there is no timeline as to when this might happen.
We love our new computer, but if we had known about this issue in advance we would not have purchased it.

Is iMac graphics card sufficient for Photoshop CS6

I'm considering purchasing a new 21.5-inch iMac that comes equipped with a NVIDIA GeForce GT 650M graphics processor with 512MB of GDDR5 memory. Will this graphics card be sufficient to run Photoshop CS6?

Your query has an answer in more details here: http://helpx.adobe.com/photoshop/kb/photoshop-cs6-gpu-faq.html. If you see this section which says
Tested video cards for Photoshop CS6
nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500, 600 series .
Hence 650M will fall under this range and is supported to run Photoshop CS6.

Imac Graphics cards with Premiere Pro cs6

Hello
I just changed over to Premiere Pro cs6 from avid and fcp 7/x. I am already sure i made the right decision. I love the interface, i really love it! and cant wait to get stuck into it properly.
I just bought a brand new, all singing all dancing 27 inch imac full spec 32gb RAM with a NIVIDA Geforce GTX 680MX 2048mb card. However pro cs6 by default is using the “Mecuary playback engine sofware only” instead of the “Mecuary playback engine Acceleration [CUDA] and i cant change it. Does it cs6 not support this card and if so will it in the future?
Any help would be greatly apericated!
Kind regards
Philip

Hi Paul
You mention last week that you had the same problem as me with your new iMac and graphics card with cs6.
I was just onto Adobe and they told me that they could not assist.
Can you tell me who you death with?
I am really keen to get this card running!
