On the competition front, Nvidia is readying its "answer" to Vega for release in the same time frame as Vega (which we all expected Nvidia to do):

The rumor/leak article indicates (to my reading) that FPS (in DX11, 12) will probably be the main target -- possibly, as usual for Nvidia, at the expense of some more forward looking features like Vulcan and Compute support. So, Vega may be a more "rounded" product able to do many (not necessarily all) of the things one expects from a modern graphics card just a little better than the Nvidia product -- we'll see.
The article indicates the Vega vs GTX1080Ti battle may come down to price and who gets to market first (and, of course, "fandom" ).
