Poor graphics on that one - you should be aiming for a HD 4850 at the very least for reasonable gaming. Or, a HD 4870 if it fits in your budget. The CPU doesn't have to be quad - a dual-core running at a faster speed is usually better in games anyway these days.
There may be better deals out there for similar money. Give us some time to find you one. It may be ideal if you could build your own - I can suggest some components off eBuyer/Scan/other. G
