Technical stuff like overclocking normally resides in the tech news here in Eurogamer, but given the popularity of this subject I thought the masses would be interested. These days it appears that gamers judge processors on a number of factors, how good it is at crunching numbers and all the normal things of course. It seems though the most important thing is the how easy the processor will be to overclock. If you have a Intel P3 600, chances are that by various ways and means you can get that to run like a P3 700, or faster. It's proven to work across the world, proven by hundreds of thousands of people and gamers. The process is called Over Clocking.
It is risky, and you risk over heating your processor, and the damage that would cause. You have to take drastic measures to ensure total safety. As the article says, "CPU's normally generate a controllable amount of heat, but overclocking increases the heat generated by the CPU and it can get out of hand, eventually toasting the CPU". Some people go to great lengths to keep their CPU's as cool as possible, "There are allot of other ways you can cool your CPU (some of them are just plain crazy, like submerging your motherboard in a non-conductive liquid, or using liquid nitrogen)". If you want to read about how you can squeeze that last mhz out of your processor, read the article.
