The NF7-S isn't really that much better in OC'ing compared to the A7N8X, and both are very stable motherboards as well. The NF7-S is cheaper however; Also, keep in mind that the new Abit AN7 will be in stores in a week or two, and is the replacement to the NF7-S. It is basically the same thing, but has some more features such as both SPDIF In and Out, and uGuru.
