Hello all,
I've been following this thread for months with great interest, as I've been considering attempting a GPU upgrade on my 27-inch, mid 2011 iMac for some time. However, this has now become a necessity, as its current one (a 6970M) seems to have stopped working (garbled image, seems to crash during boot, can't even access it from my MacBook via Screen Sharing).
I have some experience taking computers apart, so I'm not too intimidated about the process. I am, however, scared about the prospect of buying a GPU that will not work, so I just need to clarify some things:

I have some experience taking computers apart, so I'm not too intimidated about the process. I am, however, scared about the prospect of buying a GPU that will not work, so I just need to clarify some things:
- after reading all 15 pages of the thread, it seems the 780M seems to have had the most success cases. Can anyone be kind enough to tell me what I should look for when buying one? The simple fact that there are both green and blue coloured models freaks me out.
- just to triple check on this: saying that the boot screen is gone, simply means that it is no longer visible, but it's still possible to operate it blindly, right? If one has Boot Camp installed, it's still possible to boot into Windows by pressing Option, Right and Return, correct?
