Big problem now tho as the 7990 is only giving me around 46fps dropping down to 35fps in bf4 where as my gtx770 was giving me around 50/70 on same game settings?

It seems like only one gpu is working?

I watched a your tube video with a guy playing the beta with a 7990 and he never dropped below 100fps and was getting 160fps which is about right.

I have tried 2 different drivers but same results?
