Hey guys, i just upgraded my psu and i also got a GTX 550ti getting shipped to me, so i can finally have a gaming pc. i dont want to buy a new cpu but im wondering if i will be able to play games good enough with my current one(games dont have to be on the high settings). i current have a Amd Athlon 64 x2 5000+ 2.60GHz processor. im looking to play games like gta 4, assassins creed series, bioshock, maybe diablo 3, batman arkham, etc. Thanks .
