I'm sorry but while I agree GPU and monitor technology is getting improved quickly, I think you're giving some incorrect info. Ultra wide 1440p monitors cap out at 100hz right now, not 144hz. The currents cards are pushing the 100hz ultrawides pretty much to their max and the 1080ti will 100% any slack left. 4k is possible past 60hz and a single 1080 is doing fairly well at 4k as is. 1080s in SLI can easily push a 4k monitor past 60fps and Asus is releasing a 4k 144hz monitor around Q3 of this year because of that. The tech is moving fast but you're exaggerating quite a bit on how hard it is to push these new displays.
4K is not really possible past 60 FPS with current games on highest settings. And those are what the target group of gamers want, I see that basically every day.
For an example, take the latest Deus Ex: http://www.techspot.com/review/1235-deus-ex-mankind-divided-.... It is also a good example for the next statement: The heaviest games don't even get 60 FPS on 1440p, on Ultra the average with a GTX 1080 is 43. 4K is at 24, basically unplayable. Even if you were to use SLI, which is by now pretty much agreed upon to be more a hassle than worth it, it wouldn't be at 60 FPS. And that disregards that 2x1080 are/were 200% the price of a single GTX 1080 Ti, and won't be close to getting 200% the performance.
You can see that as you want, but I can pretty much guarantee that gamers, at least the segment of gamers that would even consider investing hat much into a gpu, will absolutely sprint to get a GTX 1080 Ti, if the performance increase is real. They need it for VR + 4K, or at the very least believe so.
As someone who plays things at 4k on my 1070 at home, let me add that things still look freaking amazing at 4k, even without Ultra settings. You can usually turn off antialiasing (sweet), and there are some effects that you probably might not notice (or care about) compared to speed.
The best part is, in two years (or four) when you buy a better card, all the titles that are currently new will tend to look about as good as 2-year-old titles look now. ;)
I have a 3440x1440 at 95hz (my Acer Predator X34 didn't quite meet the 100hz claim..), and 2x 980s. One of the 980s isn't fast enough to drive it properly; two work fine, but I'm almost always having SLI issues it seems. Therefore the 1080TI will be a massive improvement to me, especially as I run 2x 1920x1200s around the 34" and would like to use frameless windows - which essentially reduces the 2x cards to 1x (SLI only works in fullscreen). For example Elite Dangerous will start to stutter when only using one of the cards.
I've crunched the numbers and the 1080TI will essentially offer the 980 SLI performance at its best - and that's before the extra RAM and Pascal features come into play - as well as the reduced heat levels etc.
So count me in, especially when Vega comes out and presses the prices further south. (Alas my monitor uses GSync, so that won't be an option for me.)
FWIW I'd like to mention that the 34" screen is completely brilliant for programming (Visual Studio), which is what I use the setup for most of the time.
You can't get any games above like 30 fps on 4K monitors even without maxing out graphics options on a $350 card today. Add multiple monitors... slows to a crawl. You can hear the fans working to keep up with non-gaming tasks...
While I do feel like noticeable CPU performance enhancements have mostly plateaued, I think we are 4-5 years away from affordable and good 4K graphics cards. The choices on the market at present aren't all that amazing. You either pay a lot for meh, or a fortune for acceptable.
Nothing on the market today is like, "OMG it handles anything we throw at it without breaking a sweat..." And that's fine... it's usually 2-3 years after a game comes out that I can run it at max settings.
SLI/CF is a huge hack - only allows true fullscreen, does weird tricks to render on both GPUs, occasionally gets glitchy results and far more crashes. You do not want to use SLI unless you have no other option.
4k@60 gaming on a single card is an excellent goal. I'm running a single 1080 for this purpose at the moment and on many games it struggles and I have to reduce options significantly.
The 1080Ti should be performant enough to run 4k@60FPS on most games on a single card. The 1080 was close, running ~45-50 FPS, but this should push it over that edge.
Then there are the people who want 4k@144 and stuff who'll be running 2 of these in no time and still not getting the numbers they want...
Hopefully within a few iterations 4k@60 will get down to an affordable level. I just really want to go back to buying $300-500 cards instead of $1k cards and this means we're on the way.
I have to disagree, there are couple consumer grade 1440p 144Hz monitors (FreeSync) - ASUS MG279Q, Acer Predator XF270HU and even 165Hz one - Acer Predator XB271HU (G-Sync) all IPS. There are also VA Ultra Wide panels like BenQ XR3501 and Acer Predator Z35 with 3440x1440px and 144Hz. Technology in this area is recently progressing with decent speed.
BenQ XR3501 and Acer Predator Z35 are 2560x1080px, not 3440x1440px. The other three are 2560x1440px, not ultrawide 3440x1440px. Parent is correct that fastest 3440x1440px displays available today are 100Hz.
None of the ultra wide 1440p monitors have 144hz. Almost all of the models you listed are 16:9 monitors and the one ultra wide is not 1440p. I agree that the tech is progressing but this generation of GPUs are pushing them quite well.
Why is your focus on ultrawide monitors? I'd bet most gamers do not use them for various reasons. You may have one but it is not the standard by which to gauge the viability of the GPU market. For example, Acer has a 240hz gaming monitor out now.
Two reasons: first, the earlier post specifically called out that, "...ultra wide 1440p monitors cap out at 100hz right now, not 144hz."
Second, it's all about pixel count. While 4k is still miles ahead of even the 3440x1440 ultra-wide resolution, that resolution represents nearly as big a jump in pixel count as the jump from 1080p to 1440p.
The goal is 4k at a minimum of 60fps. Consistent 100 hz or even 144hz on an ultra-wide 3440x1440 monitor represents a solid step in that direction.
