Anything is better than the 1080 overpriced marketing "flagship."
At 4K the 1070 / 1080 are only 6% / 30% faster than the Fury X:

Historically speaking true next gen flagship used to fall in the range of 50-100% faster. Under ATI, there would be no chance that NV would sell 6600GT/7600GT/GTX560/Ti for $400-700. Too bad as that's what's happening right now. Let's hope AMD actually delivers and NV responds with 1080Ti so the market realignfs itself with historical trends of what a true next gen used to mean.
Having said that, I already have 1070 SLI and since ~90% of 2015-2016 AAA games are console ports, so why waste $ on flagships? Right now many AAA games are so poorly optimized that they often require Titan XP to max them out. Please. Imo, flagship GPUs never made less sense in the history of PC gaming. PC gaming hasn't been this gimped compared to consoles in a while. Now if you run a PS4 Pro game at 10 feet away on a 65" 4K OLED and run the same cross-platform game on a 6700K + GTX 1070 SLI, you can barely tell them apart.
Even though GPU hardware sales keep increasing and more gamers are moving up to $300-400 GPUs, let's not kid ourselves -- PC gaming industry is in a huge rut since the extra CPU+GPU horsepower is hardly commensurate with the graphics we get.
The massive performance advantage PCs have is nowhere to be found in revolutionary terms. When Crysis came out, frankly it blew every single XB360/PS3 game away. There is NOT 1 game on the PC released from 2013-2016 that will make any console gamer say "Holly ****! That's ******* amazing!" When Unreal 2 or Crysis 1 came out, PC gamers were proud of just how advanced our platform was. Today, it's very hard to pick a PC game which exemplifies the cutting edge aspects of PC gaming.To do that now, you may need to dive into VR.
The current console install base is close to 70M. The greater this install base becomes, the more AAA games will be held back by these consoles. It's literally a repeat of XB360/PS3 generation during the last 3 years. I had 7970 CF in 2012 and it sat there twirling thumbs playing console games.
I would much rather have the next "Crysis" that wipes the floor with Titan XP SLI - I am thinking 30 FPS at 1080p 4xMSAA, but 95% of PC gamers don't want that...the GPU industry is never going to be the same since they are now pushing more pixels = next gen graphics. Now it's all about 4K and later it will be about 4K 100-144Hz, then 8K. Except EA, no one is really even pushing the boundaries like Crytek did.
