I don't have two video cards in a single system at this time to test with, but unless I'm horribly mistaken:

I did verify there's a tieriary and 4th setting as well.

What this does is launch the game telling DirectX that THATS the hardware to use - same thing you do by telling windows use this hardware, launch wow, switch back. If I'm wrong I'm sure Lax will correct me .
I wish I had a third monitor at the moment to try this out and break up my 5 WoW instances into an H formation. I may very well have to go get one tomorrow. This whole time InnerSpace was the answer to our dual video card setup [w/o doing it manually]? I did see those settings back when disabled my console key [because accidentally hitting '~' can be quite annoying in game] but thought nothing of it.

EDIT:

Blah my secondary PCI-Express slot is x8 so I doubt I'll be able to do much. Got all excited and ahead of myself
