AMD drivers are better now, especially with DX12 games and again with Vulkan. DX12 should be taken into consideration, as it should replace DX11 with the next coming games. Normally.
I agree that the 1060 runs faster with DX11 games, but as long as you get more than 30/40 fps, why bother?
One last word about drivers, I prefer the Crimson to the GeForce ones. The GeForce ones are so intrusive, I don't mind sending some informations to the developpers to help them correct their drivers and make better ones, but NVidia really goes wayy too far. And they're not even as good as they were before.
