A couple things, first and foremost I can't find that video card anywhere, you sure you have it right MSI 640 TI, all I can find is geforce 640 GT, in any event I'm sure this card is not optimal for high settings in wow.
I can't post links but go to the Seagate website and click on drivers and firmware, I'm positive that hard drive of yours has an "important" firmware update available, not sure if thats the issue but it will not hurt to update it as its listed as "important".
Double check the video card as well, download something like gpuz or speccy and see what it says.
