SSAA is going to have a *huge* performance hit because of how it works. It is far more intensive than any other type of AA out there, what it does is render the image internally at a higher resolution, render it with color correction and aliasing, and then outputs it at the original resolution. It is extremely intensive, for example 8x SSAA will render a 1920x1080 image internally in excess of 16k x 8k resolution. Big big performance hit.
With all that said, its not realistic to use SSAA in a modern game such as crysis 2 or DA2. The performance hit easily halves your framerate. Its nice to have for older games, and also NV can't use SSAA within the driver (nv only has MSAA + TrSS). the only way to use SSAA on nvidia cards is tinkering within nvidia inspector, you can't enable it within the driver.
Anyway, to answer simply....its only realistic to use in a few games, I like using it in Dead Space, for example. Generally speaking, you'll see a 30-40% performance hit in most cases. I would also like to use it in Just Cause 2, but I have to wait for the next driver release to test it.
