I can never understand companies that give you a product, and then penalise you if you use it to its full capacity.
if you dont want someone using 8 CPUs at 100% then dont bloody well give them 8 cpus in the first place!!!

You mean like renting a car and taking it to a superspeedway so you can drive 150+mph?
Well, if you paid for a sports car, you kind of expect to be able to treat it like one.
Otherwise, you'd rent a station wagon.
