1080 ti sli

[Cl1362]

Is the benefit from 1080 ti SLI  about 50%

 

Is it worth the upgrade?

 

Thanks in advance?

Not alot of games are optimized for sli, causing alot of problems using 2 graphics cards. In some cases, you can see a decrease in performance using sli.

It's worth buying. Not because it's good value, but it's where you should be heading when a single 1080ti is not enough.

[Anjelllo]

Nope. More trouble than it's worth.

Mah FPS's are under 200 and I haz $800 burning a hole in mah pocketz!!!!!!!!!!!!!!!!111!!!!!!!!!!

Unless you have a 300hz monitor, 200 fps is enough. Your monitor can only project as many fps a second as its refresh rate, 600 fps on a 60 hz monitor would be completely overkill.

The titan XP has almost the exact same gaming performance as a 1080Ti...

At 4K 1080ti sli is often the only way to get true solid 60FPS in all titles that have any support without compromising settings. And really, who wants to limit themselves to 60FPS anyways.

 

I was in his position last gen with a 980ti, and I'd say the upgrade to SLI was worth it in moving past 60FPS 1440p high/ultra settings.

This. There are AAA games that need extra power on ultra.

 

There are some games where you can have up to 70%-80% scaling with good optimization and profiles.

 

Don't listen to people saying it's not worth it. Read the pinned SLI thread on this forum, see what kind of games you are playing or will want to play and make your own decision. Also, read some other forums where the % of people actually running top tier cards in SLI is high so they can tell you if they think it's worth it. Personally I've known people who have been running SLI for the past few generations and they wouldn't have it other way.

 

It all depends on what you are doing. If you are interested in ultra settings and high resolution and you have money to spend then I say go for it. Because why wouldn't you. If you are optimizing your budget though, then think hard.

As somebody who has x2 1080Ti's I can tell you 1 is not enough for 100Hz 3400x1440p.  

Also OP dont forget to grab a HB bridge!

I'll admit that is actually a bit disappointing to hear, because my two 980ti overclocked overvolted cards pretty much get me where I want to be with 100hz 3440x1440p.

 

Thought the 1080ti was right on par with that combination (maybe not overclocked I guess).

Ok, be very aware that a lot of people that talk about SLI have no actual experience, only what they have heard or read.

 

If you buy 2 identical cards and don't play obscure games, SLI support is pretty good. I used 2 970s for over 18 months and every game except Just Cause 3 and Quantum Break (shocker) had SLI support. If you have the funds, a strong CPU and a monitor to take advantage of that power (4k or high refresh 1440P) then go ahead and get it. 50% is what I would say most games sit at on average. Some games will become CPU bound purely due to the amount of raw GPU horse power, other games may sit at +30% in SLI and others maybe as high as 70% (not often)

W3 showed probably 85% scaling for my two 980tis. AC Unity at first was reducing performance with SLI enabled (unlike most games that don't work with it where just its the same as one gpu), but later patches fixed that.

 

Also obviously moba's and other craptastic titles tend not to have SLI support, but it really really doesn't matter that they don't.

Depends on what you play, only few games have SLI boost

If you're rich it's not an issue, but otherwise meh.

When I see something like this then the first question that comes to my mind is "if there are only few then you will not have a problem with naming all of them, will you?" ;-)

So much this.

 

Now, in your initial post you ask if it is worth it. It all depends on what you mean by "worth". There are people who will say that if you pay +100% the price and will not get +100% performance then it's technically not worth it. 

 

But if one 1080ti is not enough for you and you are an enthusiast who will not go an inch left with the sliders, then as with everything that is on enthusiast level, you need to be prepared to pay more in order to gain less. Some people have said that already on the forums, the last 5-10% of performance will always be the most expensive. If you don't care about that and performance is your only concern, then I think the upsides outweight the downsides. 

 

And 2x1080ti is a better deal than one Titan Xp for sure ;-)

why do people say this .... pretty much all newly released games offer SLI support, some don't have it on release, but it normally comes within a few weeks. As said above, if you're playing MOBO and eastern games then probably not, however most AAA games offer it, hell, even World of Warcraft offers SLI support!

Then my definition and your definition of "only few" are a tad bit different. There are 31 pages on that list, 12 titles on a page...

 

EDIT:

 

and the list isn't complete. For instance, there is no Battlefield 1 on it and I know for a fact that it is possible to make it work in that game. But it's an enthusiast thing so if someone wants "plug and play" without playing with profiles and drivers then for sure SLI isn't for them.

If you are running on a 60hz monitor with no adaptive sync I'd argue that SLI with any GPU is not worth it. There's many times where you'll get excessive tearing or stuttering on supported games and to me that's just not something I want to deal with anymore. However, if your monitor supports G-Sync I'd say it's absolutely worth it. G-Sync basically fixes all of those little bugs that SLI systems have and makes the experience so much better. With G-Sync and SLI, you get all of the benefits of the extra horsepower and none of the drawbacks of multiple GPUs (except maybe heat output).

 

Full disclosure: I've run dual/triple/quad GPU setups from both AMD and Nvidia solely since ~2005. Only now with adaptive sync being common would I say the experience is refined enough for the average user. Whereas before there was a lot of tweaking of fiddling needed to get things running well. That is not the case now.

mentally not enough? 1080ti sli looks better (and makes some people feel better) than a single 1080ti in the case.

agreed most part

been running sli since 8600gt

but I dont seem to suffer from stuttering on non gsync

I do run 144hz surround though
