Ok... after reading this article, i can see that overclocking my PC would be a great thing to do. i have a Dell XPS 400 Intel Pentium D Processor 820 (2.8Ghz) w/ Duel Core Technology. 1 GB RAM, 250 GB Hardrive and a 256 MB nVidia Geforce 7900 GS. Which type of Overclocking would be best; FSB or Multiplier? and how woul di go about doing it?
