NVIDIA GeForce 9400 256MB Upgrade? Or Replacement Still Available?

Yes, I know my poor iMac is ancient at this point but, I'm hoping to give it just a little more life anyway. I've been told by apple that the graphics card is on it's way out. It's been slowing down and choking on my Adobe programs. I was blaming the hard drive but that apparently wasn't the issue.

I don't know anything about the inside of an iMac - does anyone know if the NVIDIA cards are replaceable? If they even come out? I guess my next question is IF it's removable, is there anything compatible that I can upgrade to? If not, I'd be just as happy getting a refurb if anyone knows where they still exist.

Sorry for what might be obvious questions - I just don't know much. I DO know that the above model, and EMC #'s are correct. I've confirmed them on the bottom of the foot and checked that my version does, in fact, have the NVIDIA not the ATI that some models of the same year had.

Thanks so much in advance!

Apple created two versions of the logic board. One with a NVIDIA GeForce 9400M graphics processor that shares memory with the system or an ATI Radeon HD 4670 with 256 MB of dedicated GDDR3 memory.

The ATI Radeon HD 4670 would be a better logic board to get.

You really need to move up to an i Series CPU (i5 or i7) based system.

what about the mxm cards

@Levi Dance - You are limited by the systems cooling design on what will work effectively. To add to it the systems CPU will hold you back as the Core 2 Duo CPU's are not powerful enough for any serious graphics work. as well as the systems SATA ports limitations.

I would strongly recommend look at getting a newer used system if you need more powerful graphics.
