EVGA GeForce GTX 680 SC Signature
EVGA goosed the base GPU clock to 1084MHz and boost clock to 1150MHz on these cards, up from 1006MHz (base) and 1058MHz (boost) on NVIDIA's reference blueprint, and cranked the the 2GB of GDDR5 memory to 6208MHz (effective), up from 6008MHz on reference cards. As a result, memory bandwidth is increased to 198.66GB/s, compared to 192.2GB/s. The upshot to having higher memory bandwidth is being better equipped to handle large textures and things like anti-aliasing (AA) and anisotropic filtering (AF).

EVGA priced the GeForce GTX 680 SC Signature edition at $530 MSRP, or for an extra $20 ($550 MSRP), the Signature+ model comes with a backplate pre-installed for additional cooling prowess.
