I currently have a P4 2.6 with hyper threading, and 1gig of ram. I am looking to get the Athlon 64 3200+ with probably the same amount of ram. My question is, will there really be a big performance difference in the processors? The Athlon is only rated at 2ghz. Isn't that actually going to decrease my performance? What other factors should I consider? I want a really kick-ass system, that will help with some basic video editing, and photoshop work, without having to wait forever to render or convert video. Please help!
