Also, if you want to overclock a lot, you'll have to buy more high end components like ram and cooling devices. Overclocking a cpu is basically increasing the voltage and multiplier on it to get more speed out of it. The downside to that is more heat. You'll have to have excellent cooling on your cpu so that it doesn't get too hot and get destroyed.If you want to tackle overclocking on your own, you will probably need a self built computer with an "overclocker's" mobo and at least a Core XX CPU.
