Getting really bad framerate with nvidia gtx 660 ti



i have just built my gaming rig and i am really disappointed with the framerate i am getting when playing world of warcraft.
my build is
i5 3570k
EVGA nvidia gtx 660 ti
asrock z77 extreme 4
corsair vengence 8gb 1666mhz
2tb seagate barracuda hdd
i am also using a 120gb ssd

When i play on ultra setting i am only getting 2 fps.
that cannot be right. If someone could please help me with my problem it would be greatly appreciated.
