I have never done it before. I don't even know where to start. I want to try it thought because I am building a custom over the summer that I want to OC to get more performance but I don't want to try it my first time on a new computer so I want to try it out on my old computer. It's an older system so I wouldn't want to take it too far, but just see how it works and to like get some experience with it. ANy advice on how/where I should start? Thanks!
