Are we going to see normal 1070/1080's out of stock before the Founder's Editions? Not because the Founder's Edition is limited in stock, but rather that there are a lot more Founder's Editions than normal cards in the first place! Shareholders are applauding I am sure.
We shall see when reviews are up if there is an overclocking advantage for the FE. If every card can hit 2+ GHz and performance scales well, then the 1080 will be a very tempting card for quite some time! I really hope prices go down for the aftermarket versions. Imagine if EVGA sells their highest end model with the Founders tax. People will still buy them simply because they are the fastest.
I am going to be patient for the aftermarket versions. If we somehow get a GDDR5X version of the 1070 down the road, I may buy one! I simply won't be buying another GDDR5 card when Hawaii has performed far above my expectations.
If we see a real X60 card from Nvidia with GDDR5X for some peculiar reason, then it may put Polaris to shame. I really hope AMD releases something to keep prices lower. The fact that the 1080 will be the performance king for the next year really bums me out if it remains a $600+ card for this long. The 7970 and 680 prices left me with the same feeling. Once the big cards were released like the 780 and 290, then it made sense to pay the small price premium for their much better longevity.
For me the 1070 feels like what the 1060 ti should be. The only interesting card here is the 1080 for its GDDR5X. I really do think that the extra memory bandwidth over the 1070 will make a big performance gap over the years. I'd be happy with a 6 GB GDDR5X 1070 with the slightly cut down shader count it usually has compared to the 1080.
I'm hoping AMD releases a 7870XT-esque card with GDDR5X. It should be competitive with a 1070, but at a much more reasonable price. Personally, I'm waiting for 2017 for the big GPU's to come. Maybe a 4k 120hz monitor being released around then too...
