Real 2011 27" iMac GPU Upgrade Question?

Ok, I have wandered through many forums with no solid answers so I am hoping I will get one here.

I have the Radeon HD 6970m 2gb in my 2011 27" Imac.

Can I put the GTX 680MX in this computer?

The sockets on the cards (not GPUs, the cards) look exactly the same. I'd like to know why I wouldn't be able to do it. I'm assuming firmware updates etc would play a part.

Answered! View the answer I have this problem too

Is this a good question?

If you are thinking/looking for a plug & play upgrade, NO wont find one. If you are an advanced DIY looking for a project you have to and decide if the cost (can you even find one) and time (~12 steps to access the GPU) involved is worth while to you. If you do, please, take lots of pictures and notes, & create a guide for this site.

FWIW aside from size/obtaining one issues I think you'd have driver, (Nvidia CUDA software ) -depending if Apple has built that into the OS as part of support for the GPU OR put it on a logic board chip) EFI firmware problems'' dropping that new of GPU in the old box...
