I wouldn't be optimistic. 
VR needs physics, good physics with a lot of objects is only possible on gpu.
VR needs lighting, good dynamic lighting needs raytracing which is on gpu.
VR needs to shade a lot of pixels, that's work for the gpu too.
Add to that high refresh rates and you will soon realize that it doesn't matter how much power GPU has, VR could always use even more.
