Wich one of this configurations would give me more power? I already own a Gtx 690 and i run BF3 (ultra settings) 0n 5760x1080p and i get an average of 60FPS (between 45 and 90)!!
Does indeed the Gtx770 4gb of vram has 4gb ?( I ask this because it just costs a little more than the 2gb Gtx770 version) .
