You'll rock the game. The 970m is a decent viedo card, far better than any console and fairly close to a 780. CPU is fine, any modern i7 or i5 will do these days. Besides that, the specs are inflated to hell.
i7 4790 recommended!? ROFL, the consoles must run this on high with tablet CPUs that are 5x times weaker. These specs are massively inflated, probably sponsored by Intel to sell the remaining Haswell stock.
Nice system, but for 4k VRAM might be an issue. I've hit over 4GB in Skyrim with texture mods and an ENB at 1080p. A 980ti might be a better solution and could perform very similar to two 970s especially since Bethesda games are not known for good multiple GPU scaling. Also, where did you get a 40" 4k monitor I might add?
