Nvidia coined Scalable Link Interface (SLI). AMD's equivalent is CrossFire.

You won't see full 100% scaling (I.e. one card gives you 60 FPS... Two cards =/= 120 FPS).

Depending how well the game / software is programmed, you're typically looking at a 90% - 80% scale.

If the program is crap, you could see +50%, 60%, or even 0%.
