On my i7-4790K and GTX 980 ti, I can put everything at Ultra, 1080p, Vsync On, and get 50-60 FPS pretty much everywhere, dips into the 30's in very rare spots. Uncapped frames go up 80+. Disabling Hairworks, I get a pretty steady 55-60, dips only into mid 40's in worst spots. (With FPS capped at 48 to fix my microstuttering, I've never seen it move. Solid 48 everywhere.)
So, yeah, I'd say your 2070 should get a significant leg up on that. You might even want to turn AA down and try out a 1440p or 2K resolution.
