ATI 8.9 WHQL official driver
8.9
''AMD has just issued the ninth update this year for its Catalyst driver software package. Version 8.9, in addition to the usual round of bug fixes, includes a new 1080p @ 50Hz display mode, overclocking support for quad-Crossfire X configurations through Overdrive and OpenGL 3.0 support – which is limited to 10 extensions at the moment, but AMD promises it will “continue to expand support.”
