Sli improvements

[Brooke10]

Does Sli give improvements to older games, or Is it just for games that are designed for SLi. The game i am thinking of is Silent Hunter 5, where i could do with an increase in FPS

Thanks

I know i can enable it from the control panel(if i get another card) What i was trying to find out if there was likely to be any improvement.

Thanks
