When it comes to ATI hardware, one of the features we have
been after for the longest time on Linux has been any overclocking
support. Windows users have ATI's OverDrive at their disposal along with
an arsenal of third-party utilities such as ATI Tool. NVIDIA also has
various utilities for overclocking their graphics cards on Windows, but
they also provide support for overclocking on Linux. Today though with
the release of the Catalyst 8.8 Linux driver there is finally ATI
OverDrive 5 support on Linux.
