You don't need four cards. You will never need four cards. Please get this through your abnormally thick skull.
Unless you have 3 monitors each running at a resolution exceeding or equal to 1920x1080 you will not need more than one 6950 card.
Why are you getting the toxic edition? It costs $50 more for a stuffty overclock that you could do yourself anyways. You apparently know how to overclock or something already so why would you even think you need that in the first place. This is your first loving build. Be real and don't tell yourself that you need 4 cards for a stuffty monitor or that you will need to overclock your processor to 5ghz. You'll probably end up breaking your processor if you try to overclock it yourself so I would recommend staying with the default cooler so that the thought of overclocking never even crosses your mind.
Get the 932.
Why the forget do you have to be so loving angry about it? "stuffty overclock", it's good because it's a stable overclock which I can overclock more, and has a very high unlock rate to a 6970.
As for quad 6950, I was just loving asking, I was curious. Don't need to get so stuffty all over it, I'm just trying to find the best upgrade path. What if I do upgrade to 3 monitors later/ Then what? I'll be stuck with 1 or 2 6950s which won't be able to handle that much resolution.
Stop being so pissed. This is why I don't loving listen to you. You think I'm going to stick with the same thing forever, and all my parts have to correspond with what I have now. You don't understand that I'm building the best upgrade path so that my parts will be able to work out in case of any major changes. Just please shut the forget up and leave.
