Hi all! I recently bought a 27" iMac i5, selected over my preferred i7 configuration primarily because I wanted to get it at the local Apple Store and have it be easy to swap in case of screen/build problems. My 27" iMac i5 is beautiful, and hassle free. I just ordered a Dell XPS 8100 with the 2.8 Core i7-860 chip in it - that machine doesn't really NEED the i7, but it was a cheap upgrade on Dell's website. I'm reasonably confident that this is the exact same chip used in the 27" i7 iMac. So, the question - is it POSSIBLE to swap the i5 in my iMac and the i7 CPU's in my Dell? I know it's difficult (I've previously swapped an SSD into a 20" Aluminum iMac), and I know it would void my warranty, and I may well never actually do it. It's clear that I probably SHOULDN'T do this, but I'm curious as to whether I COULD. So, the question is, "Is there any reason (sockets, size, heat, speed, other incompatibility) why this swap physically wouldn't work?" and next, is there anything beyond a physcial swapI need to do to make it work? reset anything on the Dell for it to accept the i5? All thoughts appreciated!
