A lot of people over clock there systems. Most dont know that there hurting there system. Processor/Motherboard and Chipsets are all working extra hard. One reason you overclock is so your system runs faster.

If you have all that the most important thing is your OS. A lot of people who overclock are using shitty shitty Operating Systems. They use Windows 98/ME. Bad mistake that is why your overclocking because your shitty OS and it's not putting out what the OS should. If you have all that is listed and your using Windows 2000/XP or even UNIX/Linux/Novell you will see that overclocking will do very little. Just a thought something to think about.
