Memnoch - nice system!!!!!
I would also recommend switching to Win2k. Yes, there were a couple of issues with the Via chipset, but they've got most of them resolved with patches, etc.
As far as gameplay goes, MS releases Critical Update packages on a monthly basis to help compatibility with programs and games. Keep your system updated, and you shouldn't have any problems. I know I don't.

Always listen to your heart, for it will never lead you astray.
All bow and cower before the Triumvirate!!!
