I got the g840 and a gtx460 and i can say that i am not always happy with the performance , but the price is 50 pounds so what do you eexpect ? Most games run good , cod 120+ , sleeping dogs normal but dips to 25 sometimes . Amazing spiderman - high settings and its bad in terms of performance . crysis , well without dx11 playable , bf3 hard to play , unoptimised performance ,protitype2 normal-good , gta 4 normal to bad . Some games freezes for me but i got a lot od processes running but i do turn them off . But it depends if you want casual gaming it does the job done , most games shouldnt give you problems , but maybe slight performance drops etc. i for one am going to get a i5 , cabt wait !
