Hmm, 2K Pro is better than XP Home/Pro in just about every concievable way. Including gaming, if you ask me. I always got between 5-25 extra FPS gaming with 2k than XP back in the day. Besides, 2K and XP are basically identical under the hood. The only differences are a little Window-dressing, if you'll excuse the pun. :rolleyes: Let me put it this way:
Windows NT 5.0 = Windows 2000 Pro
Windows NT 5.1 = Windows XP Pro
That I know of, there isn't anything XP can do that 2kPro can't. Not only that, but 2k is faster and easier on your resources. My 2 cents...
