What GPU's are compatible with iMac 27" 2011?
I have an iMac 27" mid-2011 with a semi-dead 6970M, 1gb GPU - I only got the system to boot by disabling the GPU kernel extensions(moving /System/Library/Extensions/AMD* to a backup location = weird and slow graphics, but better than just a gray screen) and Apple has refused to fix the problem because it's more than four years old - even though it's a recognized issue.
So, I need a new card.
- Are all MXM 3.0 B cards compatible or does the card need Apple firmware?
- Would a 6970M card for a Dell Alienware laptop or another card with the same chip as one of the iMac 2011 models work?
- Where can I get a card that works? (<400$)
I've see a lot of questions and answers that dance around these questions but none that actually answers them specifically so ANY help will be greatly appreciated.
Is this a good question?
