Is this fps low in wow?

I just got a new gaming computer that i build myself and it is amazing compared to my old one. The thing is that i get what seems like unusually low framerates in World of Warcraft. I was thinking that due to WoW's lack of good graphics, I should be able to get higher fps that what I get now. Maybe its just me having higher expectations of my computer... In any case, can someone clarify what fps i can expect with my current rig using high settings, 1680x1050 resolution, and 1xAA in WoW.

Just for comparison, here are some benchmark results...
