i had the Amd Sempron 145 got it for like £30 and relly was a good cpu i mangle to overcocked it to 3.91 ghz and i was able to max arma2 with a xfx 6950 2gb at 1080p no lag or anything
its not the best but it sure can be used for gaming many people will say it can never run games but its not true i bought it thinking it never be able to run a game its ok too when it was at stock speed at 2.8ghz but it does need overclocked to get the most outa it and some Amd Sempron 145 have a second core witch can be unlocked
