The $1000 3960X is a terrible idea. It offers virtually nothing over the $600 3930K.
Dominator RAM is likewise too expensive and not better than cheaper alternatives.
The Rampage IV Extreme offers you nothing that far cheaper motherboards don't, as you probably won't be going triple-SLI (am I wrong?). Assuming you're going for the huge triple-slot 680, this motherboard will do you fine at half the price of the Asus: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128532
