Nvidia's original GeForce GTX 580 is a lightening fast card, and is the fastest thing on single GPU legs right now. So an overclocked version, like this GTX 580 AMP! from Zotac is surely going to be a beast. Buying a pre-overclocked graphics card though is like buying a car with all the options. You might not see a major performance gain, but you're safe in the knowledge that, in its class, your card is probably the best.
