Bright Side of News had an interview with overclocker Vince "Kingpin" Lucido, you can read it over here.
BSN*: When and why did you start to overclock? Can you remember what system it was?
k|ngp|n: When I first got back into computers, I got into Unreal Tournament. I don't remember where I was; I think I was at a friend's house. So I went and bought a computer, a HP prebuilt gaming computer. I set up and started playing games, pretty much spent all my time online playing games; 5, 6, 7 hours a day and sometimes even longer. And every once in a while my computer would start running really badly and I started to visit sites like Xtreme Systems and Futuremark. I visited mostly just those sites but I did visit some AMD based sites. It was mostly to get my computer to run as fast as possible.
