It wouldn't be twice as fast, you are probably looking in the region from maybe 50-70% but that's my best guess and every card scales differently. Some work better in SLI/Crossfire than others.
I would recommend sticking to one card. Less heat produced, less power consumed, less space taken up, cheaper, less chance of driver instabilities, and some games don't really take advantage of multiple GPUs, but more and more are.
But either way, I'd get one powerful single card.
Jason, I suppose you haven't been looking in the news lately The new cards by AMD are supposed have MUCH improved scaling, like even 90 percent. But its up to games to take advantage of it, so yeah, 1 card is better.
