I would say this is one of the best presentations I've seen in a long while. The partnerships AMD is building around them is looking very good. Just a few years ago I would've never thought possible for AMD to gather this much support. Lots of hard work being done there to be sure.
And... WOW!. I did not see the Radeon Pro SSG coming. 1TB+ storage directly accessable to the GPU without going through the pcie bus... VERY Nice!
