Overclocking can be a seriously satisfying experience with great results with little or no extra cash investments ... but it can also seriously damage your social life (eg. hours or days spent searching for settings to get your machine just to boot, or to keep it stable once it does load your operating system ... then there are benchmarks and burn tests to consider ).
