GIGABYTE is out with its custom-design Radeon HD 7800 series graphics cards on day one, the company prepared a Radeon HD 7870 model, and an HD 7850 one, augmented with its WindForce cooling solutions. The HD 7870 card, the GV-R787OC-2GD, makes use of a long Ultra Durable VGA+ PCB by GIGABYTE, outfitted with the company's best air-cooling solution, the WindForce 3X, which has been used on a variety of high-end graphics cards by GIGABYTE. The card is also said to feature a 5-10% factory OC.

The HD 7850 card, the GV-R785OC-2GD, features a shorter PCB, and features a more compact twin-fan WindForce Anti-Turbulence cooler. This model features a 5% OC, too. The WindForce 3X uses a combination of monolithic heatsinks and aluminum fin stacks suspended over copper heat pipes, ventilated by three fans that are slightly inclined, to reduce turbulence, and push hot air towards the vent on the rear panel. The compact WindForce cooler uses an aluminum fin array to which heat is conveyed by two copper heat pipes.
