"Catalyst 12.11 promises up to 15% performance improvements in the most modern games, such as Battlefield 3, DiRT Showdown, Sleeping Dogs, Medal of Honor: Warfighter, and more. With these improvements, AMD is claiming performance leads for all its top products, over NVIDIA's. The Radeon HD 7970 GHz Edition, for example, gains 20% performance advantage over GeForce GTX 680; HD 7970 gains 15% over GTX 670, and HD 7950 20% over GTX 660 Ti. The Never Settle driver, along with its complete release notes and download links will be updated a little later today. "
