Although it doesn’t matter to gamers buying GPUs solely for gaming, it really matters for a lot of the researchers (not just computer science, but any major that uses GPU computing), and also the professionals (using CAD and other software). They are also buying those high-end GPUs alongside the gamers, and are constantly irritated by shaky Linux nvidia drivers. If AMD gets enough support for high-performance computing (ex. deep learning), then researchers might be more inclined to switch to AMD...
