That spec is almost overkill, I barely cap my 2080 on 5mans on 1440p. WoW is very intensive on CPU, so I'd recommend adding a Noctua D15 (the black one doesn't hurt the eyes) and doing a mild, yet respectful overclock. I have a lot less stuttering and frame drops with OC on my older cpu (8600k).

You'll be alright with that setup
