I wouldn't bother with it if you're a serious gamer.
It is way better than other elcheapo cards you find around (5200 FX, 5500 FX, etc...) but for a few pennys more you can get a 7600 GS
and even then, for a few pennys more, a 7600 GT.
Buy the 7300 GS if you are totally strapped for cash (and for no other reason)
