Anyone using an ATI card will be happy to know that the latest set in the Catalyst series is now available. Catalyst 6.4 features primarily video quality improvements and an update to MCE functionality, performance increases to particular programs such as Half Life 2, and a host of bug fixes for various games and programs. There are still issues with Crossfire that are unresolved that ATI is aware of, but overall if you are a gamer this release is something you should take a look at. The full release notes are on ATI's site.
