Running on integrated with my i7-4790k@4.7GHz temporarily. The 980 ti never quite performed up to par with 1440p, giving me ~50fps on most modern games. My plan for now is to get my single 1440p PG278Q closer to 144hz on ultra. I have aspirations of adding two 1440p, 60hz monitors on the sides, so vram was a factor in selling the 980 ti to get the 1000 series.

What would you do?

1) Get two 1080s now. Then, add a third 1080 ti (Run less optimally at x8/x4/x4) a few months later and add two more monitors. This combination will still have only 2.67gb VRAM available per monitor. (UPDATE: Did not realize pascal only supports 2-way SLI)

2) Wait for a 1080 ti with more VRAM. Then, add a second 1080 ti (Run more optimally at x8/x8) a few months later and add two more monitors. If they do something like 12GB on it, that'll be a perfect 4GB VRAM split.

3) Other ideas!

P.S. I'm aware there is no info released on a 1080 ti and that I'll be nowhere near 144hz once I add two more monitors.

8GB of VRAM is plenty. Running 6k (2k triple monitor) on twin 1080s will be fine with 8GBs. 4k barely even scratches 6GB anyways.

However, 6k at 144fps on high-to ultra is still a little out of league for the GTX 1080s. However don't quote me on that. It could be that the highly overclocked versions of the 1080 can do what your saying.

However, as usual, the best of the best will be the Pascal Titan, if you can wait that long.

Quick warning though, I'd overclock the heck out of that 4790K. Pascal has been known to really push even Skylake CPUs to their limit. I heard Kyle on AwsomeSauce Network saying he was expereincing some bottlenecking with the 1080 on his haswell e test bench.

1) What nonsense is this about vram?
2) 1080 supports 2 way SLI but not 3 or 4, so two cards at most
3) No games will run at 3x1440p @ >100fps for a long time, 1080 SLI is no exception
4) Seriously, stop with the vram nonsense, that's NOT how game rendering works!

1. i havent fully read up on the 1080 yet, so i wouldnt know that it only supported two way sli
2. i specifically said "I'm aware that I'll be nowhere near 144hz once I add two more monitors" at the end of my post, so lean to read the entire post before you give a redundant answer.
3. Higher resolutions and multiple monitor setups absolutely favor more vram. I understand it won't actually give an equal split on vram, it was an example that there will be more available in general. my wording could have definitely been better, so i removed that part of my post. i am also concerned with future proofing at such high resolutions.
4. take a chill pill

on a side note i guess you answered my question since you cant 3-way the 1080.

so thanks, but no thanks.

Thanks TechyInAZ. I really only expect ~40-60fps with three 1440p. I was talking about 144hz with the single one I currently have until I upgrade to three (two 60hz on the side). that'll give me an option to play high fps on the single one when a game won't support all 3.

I haven't heard pascal pushes those processors so hard. Good to know. I have mine on a solid 4.7GHz. temp is no issue, but i have it at the max voltage recommendation. 4.7 is all I could pull with that chip stability wise.

We probably at the point that cpu barely keep up with gpu thanks to intel focus more on efficiency than IPC improvement. Seeing how little cpu improvement over the years i do think we will reach to this problem sooner or later. Hence DX12 try to solve the CPU bottleneck issue and make it easier for developer to scale their game with cpu core count. Though to me DX12 solve one problem only to create another problem on different area.

So i take it you don't want the FPS go below 40 for smoothness reason. Then how about getting Gsync or Freesync solution?

From what I've read, the 1080ti is only going to be 8Gb, so you're not going to get more coming up from 1080s. I did hear that it will be HBM2 though, and that will effectively allow for better memory utilization. Take this with a grain of salt though, until NVidia says it, it isn't true, and even then there might be small print they don't want you to know. I'd go ahead with a single 1080 and the single 144hz monitor, then maybe when the 1080ti comes out, see how well it performs over the 1080, and then make a decision, I know you know, but no one here can predict the future.

You're seriously overestimating:
1) The memory requirements of games, very few hit even at 6GB with 4K unless they have downloadable ultra textures. What does matter though is memory bandwidth, since you're pumping out that many additional pixels.
2) The amount of additional memory needed per additional degree of FOV. Geometry multiplies quickly, but textures are mostly the same so the memory increase is minimal going from one FOV to double that FOV.

If you're in no rush, just wait, maybe the AMD 400 line will have something you like, or hope that the 1080ti is released sooner than 8-14mo from now. If you need a card now, 1080 seems like a solid pick for at least your single 1440p

From the current benchmarks (like http://www.roadtovr.com/nvidia-gtx-1080-benchmark-review-performance-head-to-head-against-the-980ti/2/#gtav and http://www.guru3d.com/articles_pages/nvidia_geforce_gtx_1080_review,26.html), you might be able to hit 40-60FPS on some games even at 3x1440p with the 1080 SLI, but likely only on games that support SLI and have reasonable scaling (50% or more)

Nvidia still allow 3 way and 4 way with pascal. But there is difference between 'allowing' and 'actively supporting'. With pascal nvidia will officialy stop supporting 3 way and 4 way BUT they did not lock out such setup completely. But don't go complaining in nvidia forum when games did not working correctly in 3 way or 4 way system.
