ATI is accepting new testers for its Catalyst beta program, you can apply over here if you're interested.
The Catalyst Beta Testing program is available to qualified and willing beta testers. This program will give testers the opportunity to test all four components of ATI's Catalyst suite.
You should not participate if you are planning on beta testing on a system with mission critical data.
Not all applications will be accepted. Participation is based on ability to report accurate feedback to ATI about any problems you have encountered with the beta drivers. You may be also asked to beta test fixes or new functionality. The goal of the beta program is to give you, the end user, a great opportunity to help us identify bugs as well as help us test bug fixes. As a beta tester you will not be able to distribute publically the code that ATI provides you.
