I'm upgrading my system this week and I have a Radeon 9800 Pro and A64 3200+ on the way. Now I've heard that there are no ATI drivers for Windows XP 64. What exactly does that mean? That my card just wont work in XP64 or just wont work well? Am I better off sticking with normal XP or going to XP64 right now? This is stricly a gaming machine, mostly playing Counter-Strike, Halo, and Lineage 2.
