Good CPU. I used it for two months and alredy everythings fine. My OC is poor (only 20% more than normal values), but is enought for now. My computer dont work well only in Crysis (1600x1200, 4xAA, DX10, all setings high) - its probably too slow memory. If somebody looking fast CPU for gaming (under 250$) its good choise.
