I got rid of HT because of program crashes and instability. My GameSpy
program crashed every other time I started it. With an Audigy2 sound
card everything was going bonkers till I went to one processor. Now
all's stable. Very few programs use HT, anyway. If you look around, in
fact, some things actually run slower! You probably need to reinstall
XP from the ground up to properly engage HT, if that's what you want.
