Hello! While i saw that the benchamark results of the GT 650m are only slightly below the HD6970m's of the 2011 iMac, i am interested in your opinions in the matter of how the stock Retina Pro in general handles gaming. I own the 2011 iMac and i'm very halpy with its gaming performance, yet i find myself playing games while having it hooked up to my 40 inch TV instead. Since i thought that carring arround a 10kg machine back an forth just to play games is a bit tideous, i was starting to think that the Retina Pro might just handle my needs in terms of working and would also let me hook it up to my TV for playing much more easy. Any advice or thougths? Thanks!
