Would not put anything higher than a 650ti, 7770 or , at best, 6850, on an i3. The big misleading benchmark everyone is getting wronged over is the one Tom'sHardware released showing cpu/gpu in BF3. They benched a singleplayer movie - cut scene. It didnt even utilize the cores on the CPUs, and was a terrible benchmark. I've tested first hand you get a 20+% improvement going from i5 - i7 in bf3 multiplayer, where it actually does use all the cores. But that benchmark has spread like wildfire spreading innacurate information.
