I'm sure the guys in charge at ATI are laughing and twisting their handlebar mustaches right now saying "Hahah, if we keep releasing beta drivers we'll never have to put out an official set again! Stop all work on official drivers and just start cranking out betas, those stupid Rage3d'ers will never notice! Muhuhahahah!"
Or maybe they're working on it, and if some people weren't nice enough to go out of their way to get their hands on beta drivers for us this thread wouldn't exist. Relax, be glad that they're taking as long as they need to rather than cranking out halfassed official sets.
