I planned to completely skip this generation of cards and until now there has been almost no temptation at all. The pricing, the SLI only limitation, etc etc.
But the Ti cards are always so tempting.
The 1080 Ti is probably still a bit too new to see any solid SLI benchmarks and even trying to find solid 1080 SLI benchmarks can be a bit of a challenge. (At least they have been for me.)
Pros: Better, faster cards. 11GB vs 6GB
Cons: Pricing is still ridiculous. SLI limitations.

Look at the Titan SLI reviews...it'll be very similar to the Ti sli reviews is what I would do.

1080 ti sli benchmarks will be very close to titan x pascal sli benchmarks. $699 per card is better than $1200 per card.

I had 2 1080 FTW that I used sli and I can tell you they were beastly. I just sent them in to step up to 2 1080 TI FE and I can report back in a few days with some info for you.

It remains to be seen how long SLI becomes relevant due to such great advancements in GPU technology and also whether game manufacturers will support it in the future. However if you really want SLI then two EVGA GTX 1080ti cards are what you need.

^^^ I agree with RJ on this. I think we are really close to single GPU performance pushing 4K on high settings like it was 1080p on ultra settings. It is why I went with the 1080 TI FE. I am looking to go from triple screens @ 5760x1080 to a 34-37" 4K monitor running at least 75hz. I am hoping 120hz is possible as well, but I keep reading conflicting information on that.

While I don't disagree with any of this, my counter argument is that we're not there yet. With my current set up, a single card isn't going to really cut it if I want to crank everything up to 11. Going triple wide was an eye opener. Started with 780 Ti SC's and they would struggle on certain games at full resolution (7680x1440). Opted to go three way just to pull out that extra little bit and the difference was definitely noticeable. Stepping up to the 980 Ti's was another big performance jump. But I can still pin those cards at 100% on certain games if I slide everything to the right. I agree, single vs single it isn't much of a contest. But a single 1080 Ti vs 980 ti SLI, the 980's are going to edge it out.

Coming from 1 980 Ti to 2x 1080 GTX on 1080p I have to say it was a huge waste. I can 5k DSR some games w/o issue like GTA. Very smooth but if you game at 1080p it's a waste. SLI utilization graph at 1080p is like nothing compared to 5k DSR. 4K it would matter I assume.

I'm not sure what you're trying to achieve with this rig (resolution and frame rate, titles you normally play, etc.), so it's hard to say for sure. I would say try a single 1080 Ti and see how you like it. You can always add a second, and I'm sure it will, at the least, provide a better game play experience if not flat out better performance (FPS numbers) all together than your two 980 Ti's. I am pretty excited about the prospect of moving away from SLI for hopefully the last time ever and subbing a 1080 Ti in for my 980 Ti SLI. I had pretty good luck with my 780 Ti's in SLI. 980 Ti's have been a bit more of a struggle. Just seems to be more times when I can't utilize them. It's pretty clear Nvidias direction with respect to SLI, so I will most likely never bother run it again. Plus I am more of a 144 Hz guy than a bleeding edge resolution guy, so I think from here on, single GPU's will be powerful enough for me. Your priorities may differ.

Your counter argument is correct Dukman ... we are not there yet. With the resolution you are running 2 1080's will fall short of the 3 980's. I had a Titan XP to play with for awhile and overclocked to it's max I could not beat my best 3 way 780Ti scores. Don't get me wrong the new cards are beasts but imo it might end up being a sidestep as oposed to an upgrade  3 780sc's - 25061 http://www.3dmark.com/fs/2321623vs. Both results are on my system. 1 Titan XP - 24052 http://www.3dmark.com/fs/11468409 Having trouble finding 1080 sli benchmark results ? Here's one place http://hwbot.org/hardware/videocards Please keep in mind these are submissions from HWBot and most are likely using exotic cooling of some type. http://www.3dmark.com/3dm/12250420? 32 533 with NVIDIA GeForce GTX 980 Ti(3x) and Intel Core i7-5930K http://www.3dmark.com/fs/...bsp; 32 970 with NVIDIA GeForce GTX 1080(2x) and Intel Core i7-6950X Compare link http://www.3dmark.com/com...s/8635122/fs/10662253# As you can see the only thing that makes these scores close is the processor , graphics wise the 3 980's have it stomped. Hope this helps

But what is the gaming experience like? Of course the more cores you can provide, the higher the number spit out at the end of synthetics will be. My experience with 3-way SLI in actual gaming was garbage, but maybe I'm just too picky. I read down the thread and see OP is using 3x 1440P monitors. If you are insistent on being on the bleeding edge of resolutions, then you can always just plan on buying as much (and as many) GPU as you can throw your wallet at. It still won't ever be enough if your goal is to maximize every setting. I still have to think 2x 1080 Ti's would wax his 3x 980 Ti's in both raw performance and game play experience, but I don't have any benchmarks to prove it. I'm guessing the only way to get those benches is to do them yourself given the obscure display setup. I have done that several times when unsure on which setup. Buy both, try them, sell the loser. If you do it while cards are brand new and decide to keep your old cards you are out next to nothing and you have peace of mind knowing you made the right choice.

I wouldn't say that I am insistent on being on the bleeding edge of resolution. Were that the case, then I would be running 3x 4k monitors or 4 to 6 monitors. I just like triple wide and prefer the appearance 1440p gives me. I will be looking for the benchmarks, and it's inevitable than someone will SLI these cards.

Still overall cheaper than the Titan XP and you get two cards for only $220 more.

you can enable sli in a lot of games by using nvidia inspector. Doing it this way is not perfect but its better than no support if you have a sli build

SLI support is key. I know that's not saying much... SOS. My setup is great to ok depending on game for surround. I forgot about Titan SLI being a comparable option to 1080ti SLI. Key for me is surround gaming, not single 4k. 21:9 monitors need higher refresh and still not a big fan of curved screens. 2560x1440 on 27" is about the sweet spot. Triple 31"-32" 4K would be great, but hardware requirements would be lagging behind again.

Sorry for digging my own thread up again.
Went searching for 1080Ti benchmarks and my search string brought up this thread, but surprisingly (again) little to no decent information on 1080Ti SLI. The links that Hillguy provided above were definitely useful, but I was hoping to find some in game bench marking done. It is also quite possible that my search skills need sharpening.

I'll have to redirect you to a YouTuber making comparisons with all sorts of videocards, but mostly founders editions, he also has various 1080Ti vs 980Ti SLI comparisons. https://www.youtube.com/user/DudeRandom84/videosAnd here are the video's: https://www.youtube.com/watch?v=Or6hkyFJ1jEhttps://www.youtube.com/watch?v=wGqYEyFcoichttps://www.youtube.com/watch?v=F1SV-l-SL_shttps://www.youtube.com/watch?v=HNnSwozq6z0https://www.youtube.com/watch?v=Bb4nYvWllyghttps://www.youtube.com/watch?v=pdIt2s04KPohttps://www.youtube.com/watch?v=Mi-yzZ-lnr8 One 1080Ti pretty much keeps up with 980Ti in SLI, but if you have a game where SLI doesn't work properly then the 1080Ti will be far better ofcourse. The 1080Ti also has the extra VRAM headroom, so even if you have enough power via SLI you may be bottlenecked at some point in your VRAM, and to be honest it isn't that hard to exceed 6GB, it would also result in worse framepacing if hitting these limits. Also considering 3-Way SLI is usually working worse than 2-Way SLI I wouldn't place my bets going for three 980Ti cards but settle on two 1080Ti cards instead, having about 4-Way SLI 980Ti performance with more VRAM.

No problem, if you need 1080Ti SLI video's do CTRL+F on his video's page and type in '1080 Ti SLI', you'll find the video's you need.
