Both are great mobo but if you want something that officially support the upcoming 400FSB AMD CPU, you should look at 8RDA3+ or NF7-S PCB rev2.0, and still, both are great but Epox will be lacking nForce2 APU but it wouldn't be an issue if you already own a decent soundcard.
Anything that can go wrong, will go wrong.
