Here is a preview of the Asus RX 480 Strix:

Default as fast as the GTX1060 FE in the five games. Even with an increased powerlimit it is slower than a MSI GTX1060. Power consumption is way higher (~200W vs. 120-140W for the MSI).
Like i said: A price cut is necessary that these AIBs can survive.
Looking at the increased power limit you mention, it's beating the 1060 gaming in COD by 20%, Witcher 3 by 7%. The AIB 1060 is beating it by 29% in Anno, by 8% in fallout 4 and 6% in Far Cry Primal.
According to their average, the 1060 gaming is just 3% faster in DX11, and 4% faster than the non-MT OC. Definitely a win for the AIB 1060. Looking at the games themselves, the 1060 wins in 3 out of 5 games. That's actually not a bad showing for the 480 consider that the 480 would beat the AIB 1060 in Quantum break, Hitman, Doom, Ashes and Total War DX12 (i.e. most dx12 and Vulkan games, the strong side of Polaris, which are mysteriously missing).
Also according to that review the difference is 50 watts, not 60-80 as you wrote in your post. While it is a difference, it's just 50 watts - not something major. Note that the non max target OC is using only 22 watts more than the 1060 gaming but the 1060 is just 4% faster in DX11, so we all know what'll happen if we add in the aforementioned DX12/Vulkan games.
I actually believe that you're exactly proving and driving home the point of this thread. DX12 is not quite here. For some reason a lot of sites are still not benching Doom Vulkan, or a significant amount of DX12, and therefore AMD are still being hindered by their poorer DX11 performance and not getting enough press about their superior DX12 performance. I believe that such a review, six months from now, will have at least 2 or 3 DX12 games.
On another note, does anyone have any insight on why Polaris has such a bad showing the FC Primal? Grenada is really performing well there.
