hello everybody i had a quick question that i could use some advice on.Im trying to play diablo 3,but im experiencing alot of lag and slowed down fights.I'm thinking this is due to my old cpu. im currently running a amd phenom quad-core 2.20 GHz. I was thinking about upgrading to a AMD Athlon II X3 445 but worried since its no quad if id lose performance anywhere.....any tips would be great,as im not really knowledgeable in this area. Thanks in advance!
