Core i7-6700K 4GHz (not overclocked)
32GB 2600MHz
MSI Z170A Gaming 7
EVGA 980Ti 6GB
Samsung 256GB 840 Pro SSDs in RAID 0
5 clients at DX11 - 1080p, main at graphics setting 7 @ 60fps, rest at potato @ 16fps via slot-swap macro

My FPS drop down to about ~40-50fps on the main in BfA zones that are high population, like the pyramid area in Zul'aman (Terrace of the Chosen?) or Orgrimmar during prime-time.

* Note I haven't been subbed since the introduction of the graphics reset the other day, but I presume if I make sure they're running the new DX11 Legacy setting, they'd behave the same as they did.
