Overclocking is just a way of getting more out of your system for free so i'm all happy with it. But i don't take it to the extreme like watercooling. I think by then you're be paying more to overclock it than you would getting a faster chip anyway. I got a nice air cooled system running at about 30% faster than stock and i only payed $10 for some fans (which allowed me to get it another 10% higher). So it's worth it to a point then it's just for enthusasts.
