IMO Its a fair bit faster than regular 32bit, sure not many apps support extra speed but you can at least run more apps at once Before you install though i would just say you MUST make sure that your hardware will run, I've had great fun looking around for drivers for my soundcard and network card. I still can't find any for my webcam (too common a problem) plus a few programs have trouble installing, virtual CD drives where missing for a long time before Deamon tools got their butts into gear.
