This is a significant win for AMD, but the real winner is Intel since most Apple notebooks will continue using integrated Intel HD or Iris graphics.
We are not sure what Nvidia did to upset Apple, but this round of devices will be powered either by Intel integrated graphics or AMD discrete graphics.

FYI for anyone having trouble installing the drivers directly from AMD...I'm using Windows 10, the regular installer doesn't automatically detect you have the correct video card for the Catalyst drivers...and their auto-detect utility doesn't work either...you need to go to your Device Manager and update the drivers from there, browse to the folder where the installer extracted (usually C:\AMD\AMD-Catalyst-15.7.1-Win10-64bit or similar)
