I have two systems I consider primary - my wife's desktop and my laptop. Sadly, my laptop is the faster processor.

My stepdad just bought an XP1600, and if he ever gets his butt in gear and puts it in his machine, he'll give me his Athlon 1GHz - all he does now is sit and play MS Flight Sim 2K2 :P
