What I still don't get is I would think that the low end Polaris should still clobber Fury, and if its $300 cards vs $600 cards why won't margins collapse.

Its interesting that several articles have pointed out that although GPU cards volume has been in steady decline for years now, revenue is actually up a bit, because ASPs are up. So just like AMD has wisely refrained from a price war with Intel in the secular PC CPU decline, so Nvidia and AMD have avoided doing so also, while also in a protracted volume decline. So at least that is good so far. But now it looks like both Pascal and Polaris are launching out the gate in the high volume lower price points and its hard to see how that doesn't affect ASPs this year.
