The Radeon HD 4850 and Radeon HD 4870 series feature best-in-class performance and Linux customers were greeted by an evolutionary step in ATI/AMD Linux support. Linux users with these graphics cards now have CrossFire, OverDrive, RandR 1.2, X-Video Bitstream Acceleration, and other new functionality."
