For CPUs it's still is a 50/50 scenario I'd say, has been that way for a while, because we still have a lot of Intel users, but when it comes to GPUs, Nvidia has been dominating for way too long. However, finally we're seeing some proper competition in the GPU sector, thanks and no thanks to Nvidia's greedy tactics and AMD for their latest and brilliant line of GPUs.
Now, with Intel entering the scene, shit just got real and it's time for Nvidia to get their shit together. I hope that Nvidia takes a few big hits and learns a thing or two, while AMD and Intel acquire a bit more "support" and market share, slowly closing the gap with Nvidia.
