Question: is wow cpu or gpu intensive?
Answer: CPU - WoW is much more CPU intensive than it is GPU. The CPU you have should be fine however. Never underestimate the power of stupid people in large numbers. Threadripper 2950x | 32gig Corsair Dominator Platinum 3200mhz | GTX 1070 (Yes, I was stingy on the graphics card HOOOO!)
