Overclocking CPU (Hack 21) at your own risk

Overclocking CPU (Hack 21) is not as easy as adding more memory or upgrading the hard disk. If you have nothing to lose, you might think about overclocking the CPU. Manufacturers may not honor the warranty on an overclocked CPU. The modifications may also void the warranty on the motherboard and other components (such as video card & hard drives).
To increase performance of your PC: I would first try to add more memory (Hack 30), and then try to replace the hard disk with a faster (& larger) one (Hack 58).
