I have a 1080Ti it should be able to run it albeit without the fixed foveated rendering for whatever benign reason not worth upgrading to RTX now.
Don't know whether an i7 4790 would be a bottleneck now. I think it will be fine since IPC doesn't seem to have improved dramatically and most VR titles I have been playing don't scale to multiple cores/threads well.
Worst case I will have to upgrade perhaps to an AMD 8 core depending on the performance.
Rather try it first before upgrading.
