Are these two worth having together?

I have ordered some of these parts but not the mobo or the v card. These two are my problem. I got in a rush and found out the mobo is Crossfire and the card is SLI. Is there ever a chance of getting 2 GTX 660s on this mobo? I am guessing not. I am very new to building.
 
Solution
I don't see why the motherboard would not be able to support 2 cards. But I would recommend just sticking with a single card setup, as for SLI with those you would need a tad beefier power supply.
