humbug it's quite clear he isn't talking about now, the issues years ago are all well documented and are the reason why AMD lived with a bad driver stigma for years.
Same can be said for Nvidia, at least AMD never introduced a Driver that made your card go up in smoke, he doesn't want to talk about that.
The last time i had any sort of issues with Drivers worth mentioning was with a 6950, 2011, back when you could call them ATI.
The fact of the matter is for years now the drivers are pretty solid on both sides.
