Zotac GTX 780 AMP! Review at HardwareHeaven
 

Today ZOTAC launch their take on a custom cooled 780 with a significant overclock applied at the factory; over 1000MHz base. We will compare it to an existing "super overclock" edition as well as taking a 7970 GHz Edition, water-cooling it and overclocking well past retail overclocked models to see how it compares in game such as Crysis 3 and Metro: Last Light.
