Problems with my pro duo

Good, my name is Andres and I am new to this site, contacts to know if someone with experience can help me, I acquired a radeom pro duo, if with the new that came out they are going to say that it is a shame, but the technology goes faster than My pocket

Well I'm going to ask the question, after the last drivers, my graphics card started to have problems with the crossfire, when it is activated it is slower having problems of having slow frames and when I turn it off the games are very smooth, then it will be the graph that Does not work well or are drivers. Thank you.
