Well, Tony, you may have seen all the problems I was having running games on my machine recently. Ever since I built it last year I've had problems. But as I posted, these all came down to the BIOS version (for some reason). Now my machine is rock solid.

I would be extremely suprised if Doom 3 did not run on 2K. Every game I've tried that was made at least a year after 2K came out has worked on it. Worms: Armageddon does not work (unfortunately- that's a great game), but Grand Theft Auto 3 does (and Vice City). I can now run these games just fine, and at very high resolutions (haven't tested how high yet). I don't see any reason to get XP, especially if you can get ahold of a 2K license

So, I don't see any problem.
