Beasically, each frame is rendered in a resolution, that is bigger than your monitor's resolution and then scaled down to your resolution.

This in basically some kind of antialiasing. When using Super Sampling you can basically achieve a better quality, than with every other antialiasing mode, however you need really a lot of performance.

Super Sampling is the oldes and "simplest" way of antialiasing, every other kind of antialiasing is just a way to get similar results with lower performance requirements.

If you are already using FXAA, you probably won't see too much of a difference by adding super sampling.
If you turn off FXAA, you will see the difference, but i'd rather have FXAA on and super sampling off, for performance reasons.

You must have some serious hardware, supersampling should hit your performance quite hard. Make sure you run around a bit, swing the camera around, go to some other places, enter combat etc. You might find your framerate quite a bit more "volatile" with Supersampling enabled, even if you can stay at 60 in some cases.

Edit: Also check both without Vsync on! :)

SuperSampling pretty much requires an HD 7900 series or GTX 670/680 as a minimum to maintain ideal FPS @ 1080p... best when paired with a second or third gen. i5/i7 OCed as well. :P
