What about heating of the > chipset, when cpu intensive applications are run for tens of hours? ok.. as far as I know, celerons won't do smp without doing hardware hacks read, drilling bits off and soldering bits on. remember also that one cpu at twice the speed is better than 2 at half that of the one.
