...I'm considering the new retina MBP. Being that I had "planned" on getting the iMac to play Diablo 3 and Skyrim, do any of you see a problem with this machine being able to run those at high settings? Anyone have any experience with the Nvidia 650M? Also, I'm assuming that if this card is able to push a retina display, it would have no trouble with an external display at a smaller resolution. Is that correct? And please, don't suggest I build my own PC tower. I know they are better for gaming, etc. but I prefer to stay in the Mac ecosystem.
