very poor performance with my card GRRHHH

[Sharpie]

Im using a ATI 9800 pro on a Nforce2 chipset with a system that has 512 of ram and in Half Life/ CS i get about 20 fps when there is a lot of action. All other games run fine. I ran benchmarks (3D Mark) and it shows normal stats compared to others with the same rig. Any ideas of whats going on?

let me guess...you upgraded your video card and didn't format first?
