you can try to lower the DX level, like say go to properties and type in -dxlevel 81, cus 81 runs perfectly with a bit of lag but very playable, if you're looking for a good graphic card under 100, I suggest going to tiger direct, and look at the 9 series, 9800 gtx are quite expensive like about 120.... and up, 9600 GT should be around 80~90 dollars, I haven't checked recently,usually with Cs:S, i have a 6150 SE 400 something nforce motherboard video card, running on Dx Level 8.1, and settings either on low i get 70~80 fps, high i get 40~60 fps. with out AA GL
