I had 9600gt Green before and I bought R6770-MD1GD5 as an upgrade.how does this card fare to play games like COD MW3,Arkham City, Diablo 3, Max Payne 3, Skyrim, NFS Run, LA Noire etc. (On a medium/low combination). Also power consumption/heat matters etc. opinion. Also going to buy Seasonic 520w S12II, is this enough for the gfx?
