VR does not need all the bells and whistles of the latest open world AA game to be compelling. As long as it has 2 DP1.2 ports there is no such thing as a GFX card not powerful enough drive 4k VR @ 120hz only a game not optimized well enough. Bake in the lighting etc.
I dont think I read the "per eye" part of the title. At a per eye 4k that would have to be a big Infinite Eye style HMD with the 180degree fov to go with it other wise it would have quite a restricted vertical FOV. Even with a displayport per eye that would require either DP1.3 or chroma sub sampling which can have no loss on a pentile screen and give 90hz on 1.2
Sony Morpheus demonstrated the 60hz timewarped to 120 works smoothly so another way past the bandwidth limit could be an on board GPU that dose the timewarp at twice or more the rate of the video feed. Could especially reduce the bandwidth with eye tracked foveated rendering.
Another nice thing about higher resolutions is even if you have a lower render buffer resolution, the distortion can be done allot more smoothly and retain more detail.
