This is how I would build the system. I would also wait on the monitor, Acer will be having a game changer as a True UHD 4K panel with proper processors this holiday season, or your only viable true UHD monitor is still breaking $2K for the starter model.
This is a scalled down verson of what I am building to run multiple monitors 27" and bigger with 1 dedicated to UHD editing. If you are willing to spend a bit more, I can show you a system that will run UHD on multiple monitors at one time, but again money becomes a big factor.
Also what case are you putting this in?
