EVGA has just listed in their online store two new GTX 680 cards from SuperClocked Series. GTX 680 SuperClocked Signagure+ comes with additional backplate.
Both cards feature factory-overclocked clocks: base clock 1084 MHz and 1150 MHz for boost clock. Memory clock was set to 1552 MHz. Signature and Signature+ have standard 2GB of GDDR5 memory. They are equipped with 5 Phase PWM, which requires 8+6-pin power connectors. Recommended power supply should have at least 550 W.
Unfortunately, those cards are not available at the moment. But you can pre-order them in EVGA online store. That’s if you have at least $529.99 for SC Signature or $549.99 for Signature+.
