EVGA GTX 680 SC Signature is one of the fastest air cooled GTX 680 cards around and EVGA’s only faster card at the moment is the GTX 680 Hydro Copper, whose GPU runs at 1150MHz. GTX 680 SC Signature’s GPU ticks at 1086MHz , while memory is at 1552MHz (6208MHz effectively). Note that the reference clocks are 1006/1502MHz GPU/Memory.
GTX 680 SC Signature comes with reference dual slot cooling that should ensure quality cooling for the factory overclocked components. In order to keep efficiency and silence at reference levels, EVGA designed a special bracket with bigger exhausts for easier air movement.
Nvidia and EVGA have decided to trust the reference cooling and you’ll soon learn that there’s indeed no reason not to. In fact, EVGA’s 3 year Limited warranty, with the option to pay for an extended 5 or 10 year warranty, speaks for itself.
