GIGABYTE GTX 780 GHz Edition Review @ Vortez
 

We last took a look at the NVIDIA GTX 780 when GIGABYTE sent us their OC (Overclock) version. Today's sample looks strikingly similar save for one key factor, this version has a much higher factory overclock. As the name suggests, this GTX 780 is pre-overclocked not only to 1GHz but a full 20MHz past that mark resulting in a GPU Boost 2.0 speed of 1071MHz! This makes the 'GHz Edition' the fastest NVIDIA GTX780 mass produced.
