According to this website:
http://forum.notebookreview.com/gam...vidia-gt-640m-2gb-vs-amd-radeon-hd-6770m.html
NVIDIA GeForce GT 640M (Bottom on the range for the new iMacs)
vs
AMD Radeon HD 6770M (My 2011 top of the like 21.5" iMac)
Posts in that link say the 640M is 10%-20% better and uses less power to run. So where/how/why do you say that the 2011 iMac GPUs are better? I'd really like to know your reasoning behind this. So I and we all know the real facts.
2011 27" GPU: 6970M - 3Dmark score: 2821
2012 27" GPU: 660M - 3Dmark score: 2320
My messages were before Apple updated the store here, before we knew they had other GPU options. So that is the reasoning behind that. There are your real facts. Can I remove the mic now?
