The guy has the latest drivers from Nvidia. Stop telling the guy to download the latest drivers from Nvidia!
OP, I have the same processor and RAM, but I have an EVGA 04G-P4-3687-KR card and I run at 2560 x 1600 (better than 1080p for the noobs who use the term "1080p" in computing), and my game runs like crap in Windowed mode, always has no matter what set up, video card, or screen size I've used.
Without windowed mode, I have ALL settings maxed, and even at my resolution, I rarely drop below 60fps.
I'm assuming though that your exact set up, even using a TV as a monitor, with Windows 7 yielded better performance? The only thing that has changed is the OS?

This is my motherboard. I installed these drivers ( not all ), but I did the important ones.

Yes. Just went from windows 7 to windows 8.
This is sad and unfortunate. Do you have another monitor to try with a similar 1920 x 1080 resolution (or little larger or smaller). A monitor, not a TV? Then test it not in Windowed mode?
I've read something recently about Windowed mode and 5.3...hmm...
Na. Just the same hdtv I have been using since 2010. I also just remembered something. Even my screen saver doesn't work properly. The timing is right ( 5 min ), but it just goes black with a loading circle where my mouse is and I have to click on the screen or hit space bar to make the screen saver go away.

This is fantastic. I went to load up wow in fullscreen and it overscanned. Exited wow and now my windows desktop is in overscan mode now. Can only see half of the taskbar and everything else is underneath the outside edges of the tv. I hate you windows 8...

Fixed -
I went directly to Intel's website and grabbed the latest versions of the Management Engine, HD Graphics drivers and the INF ( chipset ) drivers. Then I went to Realtek's website and grabbed the latest Sound and Ethernet drivers.
Once installed and updated, I went into device manager and disabled Intel's HD Graphics from running so only my Nvidia 660 TI was working.
I also removed Lucid Virtu MVP ( whatever the latest version was ). Was supposed to help with gaming...
I then ran Ccleaner and Registry Mechanic 11.1 to clean up my system.
I now have 55-60 fps all the time in Stormwind now with graphics maxed besides ssao and shadows with Directx 11 enabled. But for some reason I have to leave multi-sampling at 1x. If I go to anything higher, wow will overscan my tv. Weird.
Doing all of this also fixed my movie maker crashing issue and my screen saver now works properly.
