It will get the job done in most of those games; although, you'll probably have to tune settings other than AA down a bit. It is a good value in that price-range. That said, a R9 280 would get you closer to "ultra", and 60FPS, if you can swing it. You bump up to a R9 280X or GTX 770 if you want to be even more future proof.
FYI, AA is one of the biggest impacts on your FPS. It improves the look of the game by smoothing out the jagged edges around objects/between pixels. It's usually the first thing I turn down if I'm not averaging 60 FPS in a game.
