Simple answer
Anti-Aliasing: OFF
offers the best performance.
Longer answer
POSTAA applies a blurry filter over the whole image, very little performance required but also a general blurry image. It's very similar to FXAA.
FXAA / MLAA "fast approximate anti-aliasing" doesn't run edge smothening calculations but rather applies extensive blurring. Resulting in very little performance taken but also generally in a blurry image.
MSAA "multi-sampling anti-aliasing" relies on color manipulation around objects to smoothen rather then blurr out edges. it's generally a good mix between performance and image quality. The higher the applied sampling (x2, x4, x8) the better the smoothness but also performance taken.
TXAA "temporal anti-alaising" is a technique nvidia cards use, it's very demanding, samples the actual framerate with twice as much framerate to remove shutter and motionblurriness.
There are several different methods mwo does not include, such as SMAA (very demanding hyper render with downscaled picture output (higher pixel density for smoothing)), MFAA (multi frame) , TSSAA, etc, etc.
When it comes down it just matters if it's either traditional rendering (SMAA) or post processing (POSTAA, FXAA).
From the default option from MWO it goes like this.
OFF, best performance, "edgy" looks.
POSTAA, very little performance needed, blurry image.
FXAA, very little to moderate performance needed, blurry image.
MSAA, little to moderate performance needed, good quality depending on the applied multisample (x2,x4,x8)
TXAA, falls flat since you have an AMD card.
Here is a list what is most common and what each method does:

Afaik, you can alter the methodes via .cfg files. Ask someone else beside me, tho. A lot of folks came up with custom .cfg files for literally any need (be it high performance for low end pcs, or high quality for high end pcs).
I personally only altered the LOD rendering distance and some other minor things.
You can alternatively use after effects shader such as sweet FX to make your game look stunning, it required a lot of performance, tho.
this is from my own settings, some cinematic effects, more vibrant colors and edge sharpening (after anti-alaising)
without SweetFX
with SweetFX
Noticed how crisp the details on the mech are?
