I don't know if this will help but I'll put it out there. Since you're running the 245, you have a socket AM3, which means your motherboard might be pretty able to upgrade stuff. Check if you can do SLI or CrossFire. According to my cousin, SLI/CFX helps increase FPS for high resolution games. If not then go for like a decent card. N.B.: only get two cards if u CAN SLI or CFX

The sky is the limit! Get a new motherboard, get a new case (I recommend ANTEC 300) and a good HSF (Zalman is a good brand I stick by.).
You'll see my suggestions are more geared toward a better processor. IMO I think the main processor has more to do with AAS calculations than Graphics cards, but Yurai is right in your case, your Graphics card isn't good.
Anyways hope this clears things up. Cheers!
