ATI keeps releasing new versions of its Catalyst drivers suite now up to version 6.9. There is a huge list of fixes and known issues that can be read on the posted release notes. Performance improvements should not be expected other than in 3dmark (useless) and Doom 3 engine games. The drivers should support all cards starting with the older Radeon 9500 up to the latest Crossfire configurations on newer Radeon X1900 series boards.

*Doom3 performances improves up to 9.3% due to further OpenGL shader complier and transform engine optimizations on the entire RadeonŽ X1000 Series of products. The largest gains can be seen on RadeonŽ X1900 configurations at resolutions of 1600x1200 or higher.
