I think AM4 pretty much beats the crap out of everything below the very top of the food chain, and maybe even a couple of those in many respects. I was never a fan of the FM3 (too small to gig with), but AM4 seems to be quite the little device. In fact, I can't imagine AM4 will not pull quite a few potential FM3 sales as well. It will also pull sales from the top end as it really is just that capable (for most users).
