amd sempron 3200+ processor..512 ram..ati radeon express 200 integrated with 128mb..I dont need all the bells and whistles..sound smoke etc..just good physics at a realistic speed..I have a ati 9200 128 mb card but reading about all the problems installing it I would like to use the onboard card if possible

I just built a system for a friend using a built in Radeon X200. It wasn't usable for 3D unless almost everything was cut down. If you try it, make sure you have the smoke and exhaust disabled, and use lower quality textures and/or a lower screen resolution. It will work, but the eye candy will have to be dialed down. The specs on the system I'm basing this on: Athlon 64 3500+, 1 Gig ram
