Can I put components from a 2012 iMac into a 2010 model?
Apologies since this covers something I asked in another question, but rather than ask separate questions about every component, I thought it would save time to simply ask: is there anything to prevent me putting the CPU and GPU from a 2012 iMac 21.5 inch into my 2010 model?
Basically, is there any fundamental difference in the logic boards that would prevent newer components from working?
I've read successful reports of people adding an i7 to an older i5 machine (as long as the power consumption is the same or lower on the new chip) so I wanted to know if the same could be done with the GPU. For example, I'd like to replace the Radeon 5670 with the newer 6770. The newer chip is GDDR5 whereas the older 5670 is GDDR3 - would this cause any incompatibility?
I would really appreciate any advice from someone who knows what they're talking about with regards to iMac logic boards - if it's just the components and not the boards themselves that are replaced in the newer models, I don't see why the newer components couldn't be swapped into older machines.
