That's a fairly powerful rig for gaming. When you say 'lag' I wonder how many fps you are expecting... or its noticable slowdowns.

I wanted to say "perhaps background apps eating up your memory", but 4Gigs - thats plenty good...

Memory leak via a third party app ? Run some diagnostics... Or maybe a driver issue.

Patch your games too - these games may not fully take advantage of the new 9800 GTX GPU...

I can guaranteed its third party apps slowing him down... a desktop screenshot of usual programs or system monitor screenshot would be tremendously helpful. Oddly, still no screenshot ?

Windows Experience Index 5.5 is pretty good.
