Specifically I have this graph in mind:


As you can see, a single 580 could drop down to 29.5 FPS which in my book is unplayable and not acceptable for a high end gaming machine. 43.8 from the SLI 580's is still very playable, but would still cause some tearing with VSYNC on.
Not sure what you're worried about. It's the highest performing single GPU. Look at the 6970's minimum. Also remember these are stock benches. The 580 OCs extremely well.
