i am planing on getting windows xp for my system. I was wondering if its worth the extra money for windows xp pro over home. my main use for my computer is gaming, and security features are of little concern to me. i would like to be able to use Intels new hyper threading and i know that only pro supports dual proccesors but i am not sure if this applys to the vitural processing from HT. mainly i would like to know if there are any speed or realibility differences between the two. thx
