Gigabyte GV-NX79X512DB-RH
As we neared the end of our testing, we spent a little time overclocking the new Gigabyte GV-NX79X512DB using the clock frequency slider available within NVIDIA's Forceware drivers, after enabling the "Coolbits" registry tweak. To find the card's peak core and memory frequencies, we slowly raised their respective sliders until we begun to see visual artifacts on-screen while running a game or benchmark, or our test system became unstable.

When all was said and done, we were able to take the Gigabyte GV-NX79X512DB up from it's default GPU and memory clock speeds of 650MHz / 800MHz (1.6GHz DDR) all the way up to 698MHz / 876MHz -- increases of 48MHz and 76MHz, respectively. While we had the card overclocked, we re-ran a couple of benchmarks to see how the increases clock speeds affected performance, and we saw 245 point jump in 3DMark06 and a 3 frames per second increase in F.E.A.R.
