I have no doubt that for low-end and mid-end setups, AMD's processors offer better performance per dollar even though that's achieved in a much less efficient way than Intel. However, I sure hope the new Bulldozer architecture will put AMD back on the map to compete at the high-end as well.
More than 50% of my household machines are AMD but I keep having to go with Intel for my "flagship" machine...and I'm not an Intel fanboy.
