Why the heck would someone go to 2000 instead of XP? Same hardware requirements and 2000 does not have near the hardware support. Win2000 as a desktop OS is going bye-bye in a year or two anyways. NT4 and NT 3.5 are great for network servers but as a "lets have fun and games" OS you're stuck back 2 years. Most newer games do not support NT and less and less hardware manufacturers are writing drivers for NT.
