Benchmark Reviews posted a review on the GIGABYTE Radeon HD 6850 Video Card

When we talk about different video card brands, there's always a factor which motivates us to choose one over any other. Most likely, we make our decisions depending on retail price, but there are things to consider: the bundle and accessories, factory overclocked speeds, and of course, included heatsinks and fans so that the GPU can be overclocked higher or simply work without being as loud and hot as a reference design. With this in mind, Benchmark Reviews tests the GIGABYTE GV-R685OC-1GD AMD Radeon HD 6850 video card. We've already tested some HD 6850 GPUs before, but GIGABYTE offers their newest design with the Windforce 2x GPU cooler and Ultra Durable VGA technology. Additionally, this is the factory OC version which brings 820MHz (against 775MHz) GPU Core clock and 4200MHz (instead 4000MHz) GDDR5 Memory clocks. Let's analyze the GV-R685OC-1GD model and see if it can be a serious contender against reference HD 6850 and GTX 460 graphics cards.
