I installed the beta because catalyst 13.1 was giving me serious problems with crossfire enabled in game (constant screen flashing), which 13.2 fixed. I will note, however, that I had sent one card in for an RMA and had just installed it to the board after updating to CCC 13.1 a few days prior if that would make a difference.
