iMac mid 2011 GPU intercompatibility
So, pretty basic question:
Are the four different GPUs available for the 2011 iMacs interchangable?
In other words: If I buy a 27" iMac with the 6770, would I be able to switch it to a 6970 from another similiar 27" iMac?
And even better: Would I be able to take the GPU from a 27" iMac and put it in a 21,5"? I guess heat concerns are relevant, but I'm mainly wondering if it would fit/run at all.
Please note I'm talking about only the cards themselves, not the heatsinks, as I know those are not compatible between 21,5"/27".
These cards are also 100% removable in case anyone wondered :)
