As mentioned in our review, Gigabyte announced its big brother of the GeForce GTX 770 WindForce 3X graphics card, it will be released with 4 GB of graphics memory. With its WindForce 3X cooler and Its factory overclock allowing it to close in towards GTX 780 performance it is a nice card alriggt. Next to that the dual-slot cooler will keep the card under 70 Degrees C at full load and it is totally silent. This 4GB WindForce 3x OC edition that comes factory clocked for you at 1137 MHz (Ref 1046) with a Boost clock of 1189 MHz (Ref 1085). Next to that, the GTX 770 series memory clock has been increased as well, at an effective data-rate of 7010 MHz.
The card is using the new WindForce 3x dual-slot cooler which used three silent 80mm fans. The aluminum radiator covers the VRM and even memory area. The radiator is tied towards two 8mm and four 6mm heat pipes. The cooler can dissipate 450W of heat whilst remaining 100% silent. As a result under full load this card manages to stay below 70 degrees C in our testing. Absolutely impressive.
