i recently bought a athlon 64 2800+and a geforce6800. i also recentlly found out that there are 64-bit drivers available from nvidia. my questions are these- 1.in order to use the forceware 64-bit drivers do i have to use the 64-bit XP? 2.is the 64-bit xp stable enough to consider upgrading to? and is it faster that regular xp?
