Ran the benchmark on a i3 3220 and gtx650 that my cousin has,went about seeing what this lower end gpu can do.Considering the idea of getting him the game but just wasn't sure how it would hold up.The following is results for 768p all low,outside of AF at 16x and population density and scaling distance sliders maxed....

Only occasionally does there seem to be a slight bottleneck from the cpu,card isn't always pegged but any other settings go pass pegging the 1gb this thing has and it starts stuttering.It's incredibly smooth in-game honestly.
RockStar did a incredibly good job on this port,i am impressed.Didn't expect much from the 650.
