I recently switched to team Red and purchased a AMD Vega 64 - I am extremely disappointed!
The OPENGL drivers especially are complete garbage, and most user advocate running some version of Linux which the Mesa drivers.
What a joke.
If this is not addressed soon, I will never purchase AMD again. People warned me that AMD's driver support was horrible compared to NVidia, but I thought "it can't be that bad can it?"
It can, and is.
