Hi all,

The money I had originally ear marked for a Ryzen upgrade has been burning a hole in my pocket (While Ryzen is an amazing platform, I think my Haswell at 4.5Ghz may be faster in games - which will be the primary function of this machine).

Currently I have an overclocked Gtx 1070 and game at 1440p. I was thinking of upgrading to a 4k display and picking up a second GTX 1070 (They are going for about $425CAD on the second hand market).

I have used Cross Fire in the past with mixed success. Is SLI worth it? Given that DX12 now shifts multi-GPU support onto the developer, do you think SLI/CF will continue to be supported moving forward?

I play an assortment of games - right now I am working through Deux Ex: Mankind Divided, and I already can't play on Ultra settings at 1440p (the in game benchmark shows 46fps) - playable, but not ideal)

If given the choice, would you:

1) Buy 4k Monitor + SLI 1070s
2) Buy 4k Monitor and wait for Vega/Volta
3) Wait and see if Ryzen works out its gaming kinks, and then upgrade the whole system (and stay at 1440p with one GTX 1070)

Many thanks for any input!
 
Depends on the game.
If you have the cash for dual high end cards + a higher power PSU and are prepared to research the dual card problems for each game, no problem.
If not, dont do it.

My preference is best single card thats not AMD.
Least hassle, best performance.
 
It's a hit or miss with SLI. I personally went with the fastest gpu I can afford. When SLI works - it's great. But if SLI was a car then I'm quite sure people would be very pissed when it refused to work every second morning or that you'd have to tinker with it for an hour to make it sort of drive and limp to work.
With dx12 pushing multi gpu support onto game devs seeing current landscape of game development I highly doubt they will be interested in working on making sure that multi-gpu works for the 1%. Almost every game now is released with bigger or smaller issues, bugs and technical problems. I'm quite sure multi-gpu support would be waaaay down on the bottom of their to-do list.
 
only go SLI if the gmaes oyu play are supported otherwise its always best to get the best single card possible.
 
if your perforamnce were a car it would be more like...
It goes the speed of other cars 20% of the roads, but 80% of the roads it goes 25% to 90% faster.

That Babel site refused to run direct x 11 mode on many of those games which require it for sli scaling support, and they also refused to do simple known sli enabling workarounds/profiles on others... and also seemed to have missed some sli enabling patches on others. It seems very biased considering this. Google the titan pascal sli and gtx 1080sli benchmark sites to get a more fair look.

I dug up all this info below since this keeps coming up in other threads:

=========================
There is a difference between whether SLI performance is worthwhile and viable,
and whether a particular person's parameters make sli a good choice for them.
I have a feeling a poll might not differentiate with the nuances.

To name a few considerations.. budget, existing rig, upgrade path, monitor resolution, demand high hz gameplay/aesthetics?, ok with dialing down settings (how much?) - to get high fps and hz (100+ avg) on a high hz monitor?, favorite types of games and titles, also game library/backlog.

You know my vote on sli itself rather than if it's right for you. That is your own decision.

"Though we mostly focused on games that support Nvidia’s multi-GPU technology, these also happen to be some of the most popular PC games released as of late. On average SLI enabled 63% more performance -- or 71% if we ignore Ashes of the Singularity. We'd call that a solid score for SLI scaling.

Granted, this may not convince many to spend another $600+ on a second GPU but in a good number of scenarios at 4K, it pushed performance from playable to smooth-as-silk.

Overall, while I'm not generally a big advocate of multi-GPU technology, it does make sense here assuming that you can afford it.
The 4K gaming experience delivered by these cards is the best I have seen yet. For those willing and able to drop four figures on this GPU configuration, you won’t be disappointed with the results."

-----------------------------------------------

http://techbuyersguru.com/4k-gaming...1070-sli-vs-1080-sli-vs-titan-x-pascal?page=4

"All told, both Titan X Pascal and modern-day SLI make playable 4K framerates the rule rather than the exception. But alas, TBG's motto is "bringing tech to light," and sometimes that means shining a harsh light on chasing the limits of technology for technology's sake. As we've shown, you can certainly game at 4K with SLI or the Titan X Pascal, and enthusiasts no doubt consider 4K benchmarks to be the ultimate test of a modern gaming PC's mettle. The problem inherent in this approach is that 4K gaming may in fact not be the end-all-and-be-all of modern PC gaming. That's because 4K monitors are currently limited to 60Hz, and throughout our testing, it was painfully obvious that our overall gaming experience on our 27" 4K monitor wasn't nearly as good as it is on the Acer 27" 1440p 144Hz G-Sync monitor we typically test with. Yes, the added resolution is nice when you're sitting still admiring the scenery, but once the action starts up, the tearing, lag, and just plain sluggishness of a 60Hz monitor rears its ugly head."

------------------------------------------------------

Practically every game I play on the GoTY and top pc games of 2016, 2015 and top pc games of all time lists supports SLI once the dust settled on patches and drivers. The only one I miss it on is forza 3 personally.

If you aren't getting at least 100fps-hz average (~ 70 - 100 - 130+ fps-hz band), you aren't getting any appreciable benefit out of a high hz monitor. DP 1.4 144hz 3440 x 1440 and 3840 x 2160 monitors due out later this year.
Pretty meaningless unless you feed it new, unique frames of action anyway.
We are just getting to the point (since titan pascal) where on the most demanding games a top end single gpu can do 100fps-hz average or so at 2560 x1440, sometimes requiring some features to be turned off in the game settings at that. And that is an average in a sort of vibrating blend +/- 30fps all over the place seconds to seconds so has half of the mix being 70 to 100 or so depending on the game(see example graph). You don't get really appreciable blur reduction and motion definition increases until you are around at least 100fps-hz (fps and hz) average so much below that you are getting no appreciable benefit out of a high hz monitor even if it was 300hz. Some old source games and other simpler games and some isometrics can get well over 200fps average though of course.

Both unreal engine and work on final fantasy XV are implementing SLI support, and I'm assuming the sequel to shadow of mordor.. so there should be a lot of titles going forward.

With unreal engine going for HDR and sli support there should be a lot of games in the future that support SLI just on that engine alone.

With the 1080ti giving something around 160% of performance of a 1070 pretty much in all games, what's the point of paying more for 1070sli and playing a lottery or waiting for patches?
 
I thought he meant 1080ti sli but now that I see his original post again I'd say since he already spent on a 1070 he was wondering about another 1070 for $450 instead of dropping $700+ on a 1080ti. I agree with Koween though considering budget concerns.

See if you can get $200+ for the 1070 and spring for the 1080ti. A 1070 goes for $380 - $400 on egg now new. Used would be like $228 - $240 using a metric of 60% retail for used goods +/-, but it depends where you market it. The forums on here seem to be asking $350 which is nuts to me when you can get it new for $40 - $50 more. Ebay people seem to pay OVER retail though so who knows.

I wouldn't buy any 4k or 3440 x 1440 monitor now with dp 1.4 due out this year for 4k 144hz and 3440 x 1440 at 144hz. Some games are a lot easier to render and could get over 100fps-hz to get something out of the higher hz. Otherwise I'd consider sticking with 1440p 144hz because that's where a single 1080ti is strong.

"I'm still in the mind set of getting the best video card you can, at that moment. Don't worry about SLI." Place. But SLI support has been increasingly better most games these days support it, and if you're running anything above 1080p and game new, you'll want that second card for the shiniest explosions that don't make you lag.

That being said... As far as enabling and disabling SLI, that can be done in the nVidia control panel, in windows. So it's pretty easy to disable or enable. Considering that I'm running at higher than a 1440p, I need the graphical horse power for just 60 fps on Ultra for ME:A and beyond (2 years, I hope). Eventually I'll cough up the money for SLI 1080ti :)
 
It varies from game to game. Here's a recent test with the 1080Ti: http://www.babeltechreviews.com/gtx-1080-ti-sli-performance-25-games/3/

If it were me, I'd sit on the cash until Vega/Volta comes out, then buy a monitor then. No sense in buying one NOW when you're going to really struggle to push it in SLI, and not be able to handle it with a single card.

Pretty interesting article.

One thing of note is, if you run Doom in non Vulkan, it does support SLI. I am not sure if the person doing that article knew it or not though.

..................." it’s a different engine so the constraints are different. In the case of Dishonored 2 we created a new engine really, even though it’s based on idTech most of it has been redone. In the case of Prey we’re using CryEngine and it’s an engine that’s already shipped stuff before, so it’s not the same configuration. "

I am using my first long running crossfire experience since last year, early fall. I've not had to disable crossfire one single time over dozens of games. It just works. I'm using a pair of Fury X cards, so the drivers are mature. When it doesn't work I wouldn't know cause frame rates are always good on my 1440p free sync setup and usually 50fps plus even when I run 7680x1440 with my three 1440 monitors in eyefinity. That's in freesync range and feels really smooth. Quite literally the Fury X crossfire setup has been set and forget and it just works.

I used SLI before but it was a long time back with a pair of GTX560ti and my experience was negative because of heat issues. But that's not applicable today as it's too long ago to be pertinent.
