Was a long time Nvidia user, then switched to AMD which really worked out in the long run. I was able to afford a Freesync monitor (lower prices) to fix the forever bug bear ... the dreaded VSYNC ! Now my games are a lot more immersive and run better. Of course Nvidia have some things going for them as well, but I was attracted to AMD because their more open policy. This seems to be really paying off with Vulkan as shown off in Doom 2016.
