I was wondering if anyone has made this upgrade or something similar and could give some feedback on how much Skyrim performance improved. My current specs are i7 920 @ 3.2, GTX 580 3gb, 12 g ram, SSD. I run Real Vision Enb with pretty standard texture upgrades, grids to load @ 7. My system is pretty stable, gameplay is 40 fps for the most part, although I get occasional stutter. So I'm curious if an upgrade to i7 4790k/GTX 970 would be significant for Skyrim. Anyone have experience on such an upgrade?
