Since no one else has asked, I will:
What else do you do with your box?
Yeah, we all love to play games. And we all want them to run smoothly and fast as hell.
But what else? If you run multiple programs a lot, and that includes the system tray, then hyperthreading is very hard to beat. If you play games with other programs running at the same time, like ripping mp3's, then the only thing that'll beat hyperthreading is a dual core cpu. Or a dual with hyperthreading! A full 4 virtual cpu's can do a lot of things at the same time. The real fun will be when AMD releases their dual core.
