Another thing to note is that when you crossfire or sli you do not then total the two cards vRam and say thats how much you have. You only have as much video ram as the lowest card that you have. If you have say 2 580 1.5GB, that means each card has 1.5GB of memory it can use, but you now have two cards performing the graphics computations rather then one, resulting in increased performance.
