Hi, to be honest today is the first time I have aver read about the Catalyst drivers. I'm not exactly sure I know what they are but it looks like Catalyst is what ATI is gonna call their drivers from now on, ie. like Detonators. About it being able to install on 3rd party "Powered by ATI" cards, I don't think that's possible. One of my housemates has a Powercolor Radeon 8500 and gets some weird "Video driver not found" error when he tries to install them. That's about as much as I can tell you...
