Yes, sure, it's probably going to be a great card, but that'll leave a huge performance gap, for a long time (before Vega comes out) between AMD's newest and NVIDIA's newest, which may not be good for, me at least, a PC Builder.
AMD will have the only cards on <28nm in the low, midrange, and laptops segments though. Maybe you don't care about that, but a lot of people do, and it seems like a smart approach with their tiny budget.
