I can't seem to find a single reliable source of information when it comes to comparing these two operating systems. I know windows 2003 server uses the latest nt kernel (5.1 IIRC), but that's about it.

What are their primary differences?

Security-wise?

Preformance-wise?

FPS(for games)-wise?

Stability-wise?

Usability-wise?

Driver support (including 64 bit)?

Any links or information would be incredibly helpful, because if it is up to snuff I might consider using 2003 pro as a desktop OS rather than XP.
