But it's important to remember that if the CPU doesn't break within about a day of installation, then you'll never have to use the warranty anyway. A conservative overclock will help in the most demanding games, and will reduce your CPU life from about 25 years to 15-20 years (by which time it'll likely be less powerful than what you can buy for pocket change, so replacing it will be more than viable). Overclocking is only dangerous when people forget that they need to be careful.
