We review the Gigabyte GeForce GTX 680 OC edition with WindForce cooler. Gigabyte's GeForce GTX 680 OC (WindForce) edition comes with a custom made PCB that is armed with Gigabyte's durable component selection. Cooling will be based on the latest model of their three fan WindForce cooler, which I can say works pretty darn well in both performance and silence. you'll spot two power connectors consist out of a 6-pin and one 8-pin PCIe PEG connector giving the card a little extra breathing room for overclocking. The card's base clock frequency is set at 1071 MHz while the memory runs stock clocked.
