I love hardware and all, but I'm a grump about recent advancements. Can Windows really harness dual core, let alone quad? My new dual core machine merrily churns away at 50% CPU usage max; that's one core at 100%. I've only spiked a dual core using VMWare running a dual core 64 bit virtual machine.

I think hardware has so far outpaced software that there's no reason for quad and all that. Save the money.

But everyone else disagrees, more knowledgeably at that. Does Vista Media Center really use all four cores?? Maybe some optimized version of Linux, but Windows?
