Which card would perform better in most games if paired with an i5 Sandy Bridge processor? I hope to play games such as Battlefield 3, Black Ops 2, Assassin's Creed III, Crysis 2, Medal of Honor: Warfighter (hopefully) on a 1920x1080 resolution with settings on ultra. There is a price difference, but negligible ($20 less for 7870 GHz Edition).
