Gtx 1080 ti or 1080 sli?

[MemeCop]

I'm building a new pc designed for 4k and my friend gave me his gtx 1080 since he upgraded to a titan X (pascal), I was wondering should I buy another 1080 for sli, despite the lack of support for sli, or opt for a 1080 TI instead? 

[Electronics Wizardy]

or just use a single 1080 for now. it will play games at 4k medium or high just fine with new games.

Sell the 1080 and go for a 1080Ti if anything.

You already have a gtx 1080, wait until next gen and get the 1080 equivalent.  It will likely outperform a 1080 ti by  a good margin

[Cyracus]

Wait for Vega

The next gen 1080 equivalent wont be out until like q2 of 2018 and im not that patient.

na, I rather wait for Volta.

Give me the 1080 and buy the 1080 Ti for yourself

A for effort

The support for SLI is awesome, no matter what the people not using SLI might say. 

 

For 4k I'd get a second 1080.

What games do you play and can you provide proof?  Run a benchmark in both in several games etc.

 

There is solid evidence from everyone in the techtuber/tech website community against sli

Literally just posted these, but what the hell. Can do others too.

Most of the games I've purchased in the last year or two either had SLI support out of the box, could be tweaked to work with SLI, or had a SLI profile out in less than a month. This is excluding UE4 games and a small handful of others.

 

For Honor, MGS V, FO4, GTA V, RotTR all either worked with SLI out of the box, or by simply changing the SLI bits.

 

https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_SLI/20.html

 

12 of the games in the above link work natively with SLI and require no trickery. With the proper tweaks, both Anno 2205 and Rainbow Six Siege can work with SLI, as seen here https://steamcommunity.com/app/375910/discussions/0/490124466463302280/ and here 

 

That just leaves Batman Arkham Knight and Just Cause 3, 2 games out of 16 total, that doesn't scale at all.

 

So yeah, SLI is pretty relevant. You just gotta be willing to get your hands dirty if necessary.

Noice, I'm thinking of vega and maybe I'll pick one up when they go cheap in a few years

[Monstieur]

I bought 1080 SLI and it's garbage in most games. A single 1080 Ti is way faster with higher minimum frame rate. You have to cherry pick benchmarks where 1080 SLI outperforms the 1080 Ti.

[scottiecb19]

Hi, can I resurrect this topic - I'm interested in upgrading my single 1080, and cannot decide whether to go sli or for the 1080ti. Cost wise, they'd work out about the same, maybe a little cheaper for the single 1080ti, but I'm after best performance and future proofing. I note some YouTube reviewers criticise sli configs, but others, like Linus and Jaystwocents do sli setups, and I cannot believe they would do this if there were so many issues with such setups. Any thoughts?

[xsimplyjosh]

Start a new thread please it doesnt hurt to do so. Ressurrecting threads is kinda ugh

 

i probably would side towards a single card 1080 ti personally. 1080 sli can be quite expensive at least with the 1080ti if u ever need extra performance u can add another 1080ti later on if needed... also some games can hv problem with sli compatibility so keep that in mind

[Mick Naughty]

Went sli 1080 but I'm only on 1440. 2 is better than one. Have a friend with 40~ 1080's so I got the  second one cheap. 

[Darkseth]

Then it's fine.

 

However: 1 > 2 ;-)

 SLi gives you tons of problems, sometimes horrible scaling etc (in 1440p you might only get in average +30% performance only, depending what games you play. That can be less, than what a 1080 ti offers). While increasing power consumption, heat etc.

And yea, tons of games where you  can get +0% performance, because Sli isn't supportet, or you can get such a bad scaling, that you even get negative performance (Both cards at <50% usage). It can happen (Check Jokerproductions on Youtube, he did a Sli video recently).

 

 

But yea, as long ti was cheap enough, it's fine^^" Just keep in Mind the many disadvantages.

 

1 strong Single GPU is pretty much always superior to 2 weaker in Sli/CF.

[Princess Luna]

Usually the SLI 1080 is 10fps faster than the single 1080ti but then we have all those countless "support or not support" issues, frankly I'd go wit ha single 1080ti

[Mick Naughty]

Depends on the games. Never had a game that didn't support it and always plays better. Power isn't a concern as I live in the states and heat isn't back a problem as it doesn't introduce much more.

You're kidding right? A 1080Ti is, on average, only about 25% faster than a single 1080 at 4k (less at lower resolutions).

https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_Ti/30.html

 

Many games that work with SLI often get at least a good 70-80% scaling. Doing the math, that means a SLI 1080 system will perform about 50% faster than a single 1080Ti - way more than + 10 FPS.

Okay, show reliable benchmarks that show as much because I'm very positive from the last time I reviewed it all 10fps ish was the average gain.

Here's my counter offer.

 

Show us benchmarks where a SLI 1080 system consistently pulls ahead by a mere 10 FPS and we'll call a spade a spade.
