The link shows that high clock speeds are much more important than the number of cores beyond two. You can see in the second graph that increasing the number of cores beyond two doesn't actually affect performance.
Huge oversight by Bethesda, not including support for more than two cores. This game is severely CPU bottle-necked, and we're pretty much SOL until someone comes up with a solution to this, be it the modding community or Bethesda themselves.
I find it upsetting that my rig could handle the highest settings if the game was actually coded to make use of my hardware. I thought quad-core was standard these days.
