Not doing that would go a long way towards more/better gaming hardware. Plus the hassle and technical knowledge needed to tweak the OS, install and configure the necessary multimedia and device capabilities, etc etc etc.
Just go Vista 64. Or if you're the rabid Anti~Vista type, reach out and grab a copy of Win 7 beta to use until GA.
