It's enough to check out some tests with 9500 GT and you will see, that that card isn't able to handle with AA/AF.
Tested what this settings change on 9600 GT in my HTPC.
Review from guru3d.com Link
As you see, you should be happy, if you are able to play with this card without AA/AF.

because i think if you have any nVidia 200 series GPU you will be able to run any game with the highest graphic and super AA/AF.
when i buy a game i spent about two hours trying to define the best graphics i can have , i over clock my GPU ,i close every program i opened....
for example i've bought ARMA 2 OA and it was very slow so i've reduced the graphics to very low so i can be able to play it.
it's very annoying.
