Well I'm not running my P4 (Windows 2000 Pro) in HT-mode because it slows down things not specifically optimized for HT (a very few!). 3DMark and all games run slower on Windows 2000 with HT enabled (tested with two installs). There is no benefit in running HT on Windows 2000. With XP Pro/2003 it's another story. The benefit in 3DMark and games is zero but it doesn't slow down anything and helps in those programs optimized for HT/dual processor use.
