Dual Core

I've been running Windows XP SP2 on my new dual core AMD Athlon 64 x2 4200+ for a few weeks now, and I must say it really does make a difference, but in a way I hadn't anticpiated (having run dual processor Linux and Unix systems for years).

It really helps the responsiveness of the system. Even when I load up Unreal Tournament 2K4, I can still alt-tab over to another app and the OS is snappy. If there's a desktop app that freaks out and starts churning 100% of the CPU, like a java or I'm still in good shape since there's another CPU to handle my requests.

I've noticed it's even more beneficial for Windows than it is for Linux, because of this responsiveness (I rarely ever had any responsiveness lockups with Linux, had them all the time with Windows).
