Should handle it on medium, maybe some high settings, depending on your resolution.
I can run on all high, barring one setting on medium to reduce stutter.
Wait ... I just saw you have a DDR2 9600GT. I've never heard of one before, just Googled and it does actually exist ... interesting. Not sure how your performance will be with that, I can't find any benchmarks for it, but I'd say medium settings.
One more thing - how many gaming computers do you have? I'm sure this isn't the first time you've asked about a gaming type computer which isn't in your system specs.
