Triple buffering means the card will keep three images rendered at all time, using up another frame buffer in video RAM (i.e. I use it as it theoretically increases speed at no visually detectable cost. It's not noticably uglier, nor is it really noticably faster with anything newer than a HD 2x00 series card. AF optimizations results in slightly faster anisotropic filtering with the loss of non-oblique texture filtering quality.
