Low FPS in WoW

[imperiects]

I am trying to figure out why my FPS is so bad wen playing WoW. Every other game I play (BF3/4, Titanall, Dark Souls 2) perform flawlessly. I friend of mine just built a similar PC and he pull 70-130 fps in populated areas. I can only get that if I'm staring at a wall.

AMD FX8120
ASRock Fatal1ty 990FX Killer
GTX 770
2x8Gb DDR 3 1600 corsair Vengeance
SDD/HDD Hybrid 1Tb

I have tried reducing the cores from 8 down to 2 (2 at a time) and it didn't help performance. I have all settings set to high performance.
