It's true, you need either server or XP and a MB that supports it.

Win 2000 pro will only recognize 2 cpu's, being the first CPU and its logical cpu. So basically by sticking to win2000 pro you're only using 1 cpu and its HT core. If you disable the HT in your bios, you should see a performance increase as then you're using 2 cpu's, but without the HT benefits.
You'll only use the full potential of your dual xeon if you switch to Win2000 server or to win XP pro. In your case I think that upgrading to XP would be the cheapest route to take...
