It's unlikely you're going to get perfect GPU scaling while using SLI, but the 780s and their drivers are pretty good, so I'd expect 180%-190% depending on your settings.

By separating the GPUs you'd effectively have twice the video RAM (since it's mirrored while using SLI) and the full 200% use of your GPUs; but, you'd have to use a special Window Layout which would keep specific clients "attached" to their monitor because swapping clients between GPUs that they're not being rendered on will cause a loss of performance on some level. And if the bug in the WoW client still exists, you can't use DX11 on any monitor except your primary monitor.
