Gigabyte sent us their OC version of the GeForce GTX 770 and GeForce GTX 780 graphics cards, equipped with their proprietary WindForce cooler. We tested both extensively and compared them to the other 770s and 780s we've had our hands on.
In the past we haven't received many cards from Gigabyte, but that seems to be changing with the arrival of the Gigabyte GeForce GTX 770 OC and GTX 780 OC. In case long-time readers are wondering why we frequently reviewed Gigabyte motherboards but not their graphics cards in our round-ups, it's because they're actually two different business units.
The Gigabyte GeForce GTX 770 OC, or the GV-N770OC-2GD as it's officially called, is of course based on the GK104 GPU like all other GeForce GTX 770 cards. The GPU runs at 1137 MHz with a 1189 MHz Boost clock, compared to the reference card with 1046 MHz and 1085 MHz. The card has 2 GB GDDR5 video memory running at 1753 MHz, which is the same as the reference card.
The distinguishing factor of this card is the WindForce cooler. It's a dual-slot cooler with two large aluminium heatsinks connected via heatpipes, along with three fans. At Computex Gigabyte informed us that the WindForce cooler is a relatively new design intended to combine better performance with less noise.
The card has the standard monitor connectors of two DVI ports, one HDMI and one DisplayPort. On the back there's a PEG6 and PEG8 power connector, and there are two SLI connectors for combining multiple cards.
The card has an average price of £ 328 / € 378, but you can find it for a little over £ 310 / € 350 already.
