The game is simply not very good for steady performance. If it's only for wow, I would not buy a 144hz monitor, unless your current monitor died or something.
144hz monitor make more sense on fast paced action games. I never tried one so I can't be sure if it gives you that much more, but I guess it would, as back in my Counter-Strike 1.6 days, my CRT 90hz monitor felt way smoother and better than my Samsung LCD at 60hz.
