I agree with 220racer, the 5770 is your major bottleneck in this setup, but it's a decently fast card for resolutions at or below 1920x1080. If you want to ratchet up performance, a card based on the new 69xx series cards from AMD/ATI or a GeForce GTX 5xx series (560 if you can wing it) would make it a screaming box. The CPU is fine, the line gets a little hazy between Intel and AMD when you start pumping up the resolution and the more expensive video cards. Lower resolution / lower detail gaming will be fine on that 5770 however.
