I have this set-up. As stated above, going with high instead of PCSS will yield you 60+ FPS average. Going with Ultra instead of HBAO+ will get you even more FPS. I think it's a question of driver and game optimization at this point, both of which can be worked on prior to launch. I can't tell the difference between the settings.
I'm more concerned about G-sync frankly. I can't prove it, but it doesn't seem to be working.
You can check if G-Sync is on by enabling the overlay from the NVIDIA control panel G-Sync -> Display (top bar) -> G-Sync indicator.
