With their GeForce GTX 780 Ti GHz Edition, Gigabyte has launched a custom GTX 780 Ti graphics cards, which features quite a massiv factory overclocking. Other than that this card comes with Gigabyte's Windforce 3X cooler, that features no less than three big fans on top of a huge fin stack.
A closer look at clock speeds reveals that this card has been overclocked to a massive 1'085 MHz baseclock and 1'150 MHz boostclock. Keeping in mind, that NVIDIAs reference design recommends 875 MHz baseclock and 928 MHz boostclock, we see that regarding baseclock there is a 210 MHz frequency bump and in case of the boost clock it's 222 MHz, which is even more. Unfortunately Gigabyte decided to not touch the memory clocks. In this case the manufacturer sticks to the NVIDIA reference design and clocks the chips at 7.0 GHz.
In order to keep this heavily overclocked chip at low temperatures, Gigabyte equipped their GTX 780 Ti GHz Edition with the Windforce 3X cooler, which features no less than three big fans and a huge fin stack. According to the manufacturer, this cooler is capable of removing 450 Watt of dissipating power efficiently at acceptable temperatures.
Unfortunately there is no information on pricing these days, but we're quite certain, this card won't be cheap.
