MSAA off and no HBAO = not max settings, by the way
As for rather the 550ti will handle it or not, the biggest question is: what resolution are you talking about?
720p? Probably. Any resolution above that? No. 1080p? Not even close.
I played it at 1080p with no problems, it could handle it with it all turned and the framerate stayed about 35, I did have a big overclock on it though.
