I remember reading various reviews on HT when it first came out, how it actually slowed down programs that didn't utilize it. But when setting up my new computer yesterday, I went to turn it off, and the motherboards message actually noted that it should be used for winxp and linux 2.4.x . So, if winxp utilized HT technology, does that mean it will make use of it when running my apps? Or is HT dependent on the app that is running? I'm just trying to get the most performance out of this box. I know linux can use it just fine, but I'm not sure about windows (and I don't want to turn it on and off everytime I reboot). So if anyone could help me with this a little that'd be great. thanks.
