I like XP Pro as well.  It has been very stable for me and the only real problem I had was with CD Creator and I had to upgrade it to work with XP.  It seems that networking is stronger in Pro and if you are hooked up to a LAN Pro is much better.  
Hey Omega, I'm not a heavy game player but the drivers on on this site VooDoofiles.com work well with my VooDoo 5.
