Oh and thanks Jack for wanting to do that test in the future.
I do have a 790X board with a brisbane 5000+ BE, and similar ram to what you used, but sadly I only have a 3850 at the moment, probably not enough to make the snow level gpu limited in the way the gpu was the limiting factor in your benchmarks.

What I find strangest is that

1. at very low resolutions (completely cpu limited) intel wins
2. at a middle ground (high resolution, standard details, gpu limited) amd wins
3. at the very highest details and resolutions, it's a tie.

I could understand how, when the gpu has to work very hard(#3), bandwidth requirements between the gpu and cpu are lower than a scenario in which the gpu can pump out much more FPS at a fairly high resolution, due to limited detail level.(#2)

But it stops making sense when intel wins at those low resolutions. Isn't that the situation in which the bandwidth/architecture advantage seen at #2 should show as well?
