I have a 2800+ and a $200 (probably better out there now, or this is cheaper) Geforce fx 5600 Ultra, and 512 mb of ram. I am an avid Raven Shield player (One of the most graphic intense games out there), and I can run with some of the best players in the United States. 2800+ and a decent graphic card (No less than a card comparable to mine) will suit you well.
