its a pretty sweet game, i got it free with my video card but it's worth the money to buy it. the only reason why i say that your card won't be able to play it on high is because my 7800gt could barely play it on high with everything up there. i think that's because i pushed EVERYTHING up to high (16x AA, etc), and i think my 7800 had some issues. but whoever said that if you can play FEAR on high then you can play quake 4 on high is prolly right.
