At present my gtx470 is gr8 with my 955 with very little bottleneck(usually above 95%,my 955 is o/c to 3.9 and my 470 @ 7,60)currenly playing crysis 2 and getting between 40 -60 fps,as i can get about £140 on the bay,is it worth upgrading(and selling the 470 while i can)to a 7950 or equivalant?or just keep till it dies,im only a casual gamer and dont play online
