I have a little bit different rig, 4790k, but went from 2 780ti's to an asus posiedon 1080ti, 32gb ram, and closed loop water cooling. Stable 4.6 ghz on the processor and the 1080ti is always above 2ghz. Triple 1080p ips monitors or cv1 rift it performs very well with the last few updates. 60 frames capped with almost maxed settings on the monitors, so you might want to upgrade your gpu first. You might be surprised by the difference![or not].
