I don't understand the obsession with overclocking. Yeah, chips are torture tested at a high speed, and the ones that don't pass usually get stamped with a slower speed.
But when you OC something...well, there isn't any free lunch. Running it higher throws heat into the equation, lower battery time. With the advancements in processors, gadgets are becoming throw away devices in a year. Seems everyone I see always wants the latest do-dad anyway, so why screw with it?
