I have read 30 reviews and benchmarks about ATI and Nvidia's top cards. Some said ATI's drivers were rarely updated and unstable. I have an ATI now, 9600, drivers seem ok to me. Planning on getting one of these two: Radeon x800 xt PE PCI Express - want be out till December, I think. More expensive. Geforce 6800 ultra 256MB - have read it is a bit slower and not as good as ATI. Have also read it is faster and better. I have a 3.4 P4 so I can run either one. Any advice?
