Wow, hold the phone here... a new update says that this original post does NOT apply to anything. Instead, AMD is simply working with DICE and EA to get the BF4 drivers out day one. This deal is NOT exclusive and Nvidia won't be left out to release a driver post launch.
So, at the end of the day, no matter what is in your PC as long as it isn't a potato, you're going to have support for BF4 on day 1.
