Bootcamp, XP, and Team Fortress 2

So if you play Team Fortress 2 (and what self-respecting gamer doesn't!) and you happen to be one of the crazy people doing it on a Mac Pro running Bootcamp here's a tip. With the latest update to Bootcamp (2.1) it seems to cause a huge issue for me when running TF2. After about a minute of game play the whole thing locks up. Video drivers? Possibly. I checked and noticed I was still running SP2. You're not supposed to go to SP3 until after the Bootcamp 2.1 patch. So I applied SP3, rebooted and ran TF2 again. Magic! Everything works as it should.
