direct download link from AMD's site for the Catalyst (Crimson) 15.12

Like eckmar say use the newest drivers and I 'll take it another step that's bad advice claymore gives on what drivers to use because some cards are not supported by the Catalyst (Crimson) 15.12 and those drivers can be the main problem in some cases and tomorrow if what I read is right there is a new drivers releases coming form AMD that will be awesome . but well see tomorrow .
And drivers do matter in how they run the cards they power and the software those cards run .
I do not recommend using this wagnard mobile software. It deleted a MF.dll file and I couldn't install neither the 15.12 crimson nor the current one.
So I had to recover my SO with a backup recovery point.
