Our mild 9% overclock allowed for a shy 6% performance gain as the frame rate increased by just 2fps. This didn’t do a whole lot for the Radeon HD 6970 and still meant that it was much slower than the GeForce GTX 570 in this game. The Radeon HD 6970 only saw a 1fps performance gain when testing with Crysis 2. On Dirt 3 the Radeon HD 6970 enjoyed an extra 5fps for a 7% performance gain. This was enough to knock out the GeForce GTX 570 running at stock frequencies. The Radeon HD 6970 also managed an extra 4fps in The Witcher 2 for a 6% performance increase.
