7600 should be fine, i got a 3800+ with an overclocked 512mb 7900gt and its run all the unreal engine 3 games really easily maxed out. apparently geforce 6 series can even run UE3 without too many worries
I cant even run UT2004 at the moment.
No idea why, when I first got this computer not even a year ago, it ran it sooooo smoothly. But I'd like to get UT2007, because I do play whats actually in the game, not just the mods. In fact im less of a mod person.
Just... need... the... computer... Which brings me to a point. After UT2007 is released and you get a new computer capable of running it. How long after that until you will need a new computer to run a newer game? That sucks
