I assume that although my cpu's utilization never passes 55% that it's capping in some other way (sadly, I don't know how to monitor that). All I can tell is if my gpu is capping out or not.
The three places I just tested where my gpu wasn't capped out but had low frames were AV (15v15 @ 35-45fps), Ashran (full zerg @25-35fps), and SW (60fps with tiny dips)
My settings in the game are 1920x1080 CMAA, turn the settings slider to 10 and then bring down shadows and ground clutter to their lowest. View distance / Environmental detail are then set at the pre-Legion max of 7/10.
I hope this can be of some help with your decision making process.
