Just the overclocking street cred alone puts this card into the upper crust of GTX 580 video cards for good reason. The overclocking results achieved with the GTX 580 DCII are the highest I have reached out of the five-odd GTX 580 cards I have tested. No small feat when you look at it. ASUS has this card equipped to run the numbers with its exclusive SAP power circuit. Run the numbers it did on the GF110 core. I was able to reach a stable core clock of 979MHz, or almost 200MHz over the as-delivered 782MHz.
