a bit better but I'd suggest the 6600gt.
My old system was a athlon xp 3200 and a nvidia 5700le. I now have athlon 64 3700+ and a nvidia 6200.
I can play new games at medium settings but not high detail, it becomes jittery and freezes on high detail.
I want to upgrade but my power supply would need replaced to, so I ain't bothering.
