I would not say overclocking is an ego-trip. buying the fastest thing on the rack, and then showing it so all can see you have the fasted... that's an ego trip.... which then makes overclocking very much similar to yanking the rug from underneath that Ego....
Overclocking can do it all....
it can be very cheap, as in[axda1800+k7s5a] + a little bit of bios action and you have yourself a pretty proper clocker.....
It can also be very expensive, obviously.....
it's mostly up to the individual, what they make of it...
as for overclocking not really worth it..... I dono, I'd say saving about $250 each time I buy new CPU is pretty much worth something...
