Nvidia application profiles

Hello, since steam for linux is out , and most of the games i play are being ported to linux, i decided to finally delete windows.
One thing i noticed in the nvidia drivers is that in windows there are application profiles, and i can decide if i want to use, lets say, sli on a game and not on others, games like serious sam 3 perform better with sli, while source games perform better on a single card. Is there any way to do the same in ubuntu?

Im currently using the 313 drivers, 2 460 gtx cards, 8gb of ram and a i7 intel processor.

Thanks for the help.

Moved to Hardware forum.

Anyone?
