We've already looked at the GTX 470 and maybe you think it's pretty good. You just wish that it had a bit more power. At the same time, you don't want to fork out GTX 480 money which is quite a big jump in price.What do you do? You overclock! Which is exactly what we're doing here today. Sure, the card runs pretty warm already and the fan is quite loud, but let's be honest; overclockers don't care about that stuff. At the end of the day, if it gets through the benchmark or your games, then all is well.Before we get into the results of the card when overclocked, we’ll have a quick look at how we went about overclocking the card and what we managed to achieve as far as the maximum overclock went.
