1080 SLI vs 2080/2080ti

[Phyxia]

Hiya.

Currently I have a EVGA 1080 Classified. Serves me well, but I wouldn't mind an upgrade. I have found a 1080 classified out for 410 USD which is pretty alright where I live. I am aware of the possible problems with running SLI but I quite enjoy the looks and feels of having two massive cards run together. (Got the power supply to back them up and overclock if I wanted too). The new 2080 in my country is approx 1 000-1 100 USD, and the 2080ti is around 1 400 USD. I'm currently playing on a 1440p 165 hz G-Sync monitor.

If I were to go SLI would it be alright usage of my money or am I fooling myself by going for SLi over a new gen card? (I already have the EVGA HB SLI bridge if it matters)

At most it's 30% increase compared to a single 1080ti, but not all games are supported or optimised for SLI. 

Meanwhile a single 2080ti = 25% - 35% improvements over 1080 ti out of the box. DLSS would make it even better.

I would look for examples of a SLI setup for the games you play.  You may have to tweak some things to get things working as you want, but if all you want is more FPS then you may be able to accomplish that with SLI.  Many will tell you it isn't worth the effort, but there are a lot of folks that will say the opposite.

I get that it's a better upgrade with a 2080ti but it's also a pretty huge price increase. Would like peoples input on whether having the SLI configuration would be worth my time. A 400 buck investment is quite affordable versus a 1400 one.

I would rather sell that card u have and get a used 1080ti instead.

I didn't list that alternative considering it might be a tad difficult selling the card. After the announcement of the new RTX cards the marketplace in my country is pretty flooded with 1080's. I could maybe sell it, but not for a fair price I would guess. This also means I'd probably haggle down the price on the 1080 I'm looking at

[Frankenburger]

I would wait for the NDA to lift on the RTX series before making any purchasing decision.

 

There's plenty of games out there that are SLI compatible, as well as user created driver configs that help expand compatibility. Also, there's a number of helpful people who can help with tweaking various SLI settings, especially over at the 3dcenter SLI megathread.

 

That being said, if the RTX series ends up being a small step over Pascal, SLI is definitely an option if you're willing to do some legwork to get the most out of it. As long as the games you play are SLI compatible, either officially or unofficially, then it would be a worth while upgrade.

I sold my 1080 for 380$-50% promotion ebay fee= around 350$ & i got a 1080 ti for 510$+50$ ebay bucks.

510-350=160$ i paid for a ti upgrade & if you want to count the ebay bucks i guess around 110$.

 

If you play it right on ebay just get a 1080 ti. evga , ask them if they have the original invoice, so if anything you can RMA it to evga.

Thats just me i'm one of those person that every time a new gpu comes out i buy, except for titan card because of the price & since the rtx 2080 ti= 1200$ i'll pass this year. If the rtx 2080 ti were about 850-950$ i would buy.

Sli is dying. 

 

Probably, even a 1080 ti would be in average faster than 2x 1080 - considering most games don't even scale with Sli anymore, and those who do, scale with 20-40% only.

 

Look at that: https://www.3dcenter.org/news/sli-performance-der-geforce-gtx-1080-ti-wenig-ueberzeugend

 

Average with ALL Games tested, 17,4% more performance with 2x 1080 ti in WQHD.

Still only 34% more Performance, if you ONLY consider the Games that scale positive with Sli.

 

Thus i think. even a regular 2080 will be a MUCH better Choice than 2x 1080, in every thinkable way. Performance, Noise, Power consumption, Problems like Micro stuttering, driver profiles etc.

https://babeltechreviews.com/the-50-game-gtx-1070-ti-sli-review/3/

 

" Out of the 51 games that we tested, we are only going to count 50 as Conan Exiles is still in early access and will not be released until March.  Seven games scale negatively with SLI and three more games have mixed scaling results depending on resolution.  Four other games need to be played in DX11 which is generally not a negative when an alternate API is available.  So eighty percent of our 50 games – 40 games – generally scale positively with SLI and most of them give solid performance increases depending on the resolution.  4K often sees the most benefit where it is mostly needed.

If you are quoting a site that is quoting Babel Tech, might as well post the updated chart.

But it doesn't play as good for the "SLI is dying" rhetorics, I know ;-)

 

EDIT: Ninja'd by @Frankenburger ;-)

[SolarNova]

if it were 2x 1080ti's yes, but 2x 1080's ..hmmm nah.

 

1080ti is 'probably' more or less the same as a 2080 non ti.

So 2x 1080ti's would be much better.

2x 1080 non ti's would maybe be 20% better than a 2080 in SLI optimised games.

 

Again take this with a pinch of salt, we just dont know yet the actually perofrmance of the 20 series.

 

So i would wait for benchmarks.

But they wouldn't be moving towards NVLink if SLI wasn't dying. /s

EBay is not a good option where I live. Gotta pay 25% extra when getting it from a foreign country

Ill prolly pick up a pair of 1080ti's for $800. Will perform better than an single card in every game I play and will be cheaper. 1080's wouldn't be too far behind but depends on use. Something like 1440 less may not be worth it. Do a lot of "3k" myself so a single card wont be able to do that compared to two.

[AngeleJR]

Upgraded my 1080s for one 2080ti and I think that it is the best damn decision I've ever done. I'm done with SLI bullshit. Games not coming out with SLI profiles and always trying to find a workaround just to get shit working. Performance is better in my opinion. At least I don't have to deal with the microstutters with SLI active.

first rtx card too slow i return a rtx 2080 cause the gains are not there yet nor are many games btw 2 1080s beat 1080 ti everyone and btw this 25-40% per card in use vc wrong i have many sli games doing 60% to 90% per card in use at same time the 20 40 that was 5 years ago when most games could  not push sli

Those frames are that good though. 

Not in the games I play anyway. Dont see my system keeping up with 2 1080’s though.
