CrossfireX + Triple Monitors

[TotalLamer]

Now, I know you can't run 3 monitors with CrossfireX. My question is this. I just got together a new rig running 2x 4870x2's. My plan is to run my main monitor off of this, and then add in an el cheapo card like a 4670 to run the two secondary monitors. Will this work? This is my motherboard:

I know I have room to fit another single slot card in one of the free slots, I just don't know how it would work as far as PCI lanes / drivers would go...

Another option. They also make a slightly cheaper VGA version, if you don't need DVI.

No, see... I don't want to turn my 3 monitors into one big "virtual" monitor like that does... I want each one to be it's own seperate desktop.
