sli worth it

Well, if you have that kind of money go for it. 

but if i am not wrong i need only that kind if refresh rate in fps games right?

[App4that]

Two schools of thought, fps and resolution. If you want the highest resolution, you have to give up fps, if you want the highest fps, you have to give up resolution. Why 1440 at 144+Hz is the sweet spot in the middle, best of both worlds.

but 4k 144 hz is now possible isnt it?

Depends on the game, but for AAA titles not yet.

yeah thats for sure but AAA games can reach 60hz atleast and games like cs go and overwatch which actually need 144hz can

Unless you're trying to feed a 144hz 4k monitor, then good luck finding a CPU that can keep up LOL. 

You've said this in another thread before. 1080ti in SLI shouldn't be bottlenecked by any decent CPU at 1440 144hz (depending on the game). Please stop spreading the misinformation that you need 4k to utilize 1080ti SLI without CPU bottlenecking, since that's just not true.

He's not entirely wrong though.

 

I have a 1080Ti SLI system, and trust me, there are more games that scale better at 4k than 1440p.

 

That's not to say DSR, MSAA, or SSAA couldn't be used to increase the render resolution to get more value out of the two cards, but I think anyone who sticks with stock in game settings at 1440p is in for a big surprise with a 1080Ti SLI system.

I'd have to agree with the last part. If you're buying any sort of high end GPU/SLI setup and you're running stock settings, you're a fool, and are most likely new to PCs.

I'd go sli. Single cards are still too weak. Every game i play supports sli so I'm not worried about it. 

[apaar123]

Can anyone give me a list of games which does not support sli or atleast some of them and can they run fine by tweaking some settings?

[App4that]

Only games I have found have issues if you're using SLI is War Thunder, and No Man's Sky. In both those games just one of my 980ti can get over 100fps at 1440.

And what's the framerate with sli?

Depends on the game and driver. I get anywhere from 20% to over 50% scaling. Quick example though.

From what I have read and saw gtx 1080ti sli isn't much of a improvement. I will probably buy single top high end GPU and then upgrade in 2-3 years to next one. Maybe one day we are able to reach 4k 100hz without sli

That's BY FAR the best way to do it. I paid almost 700 bucks for my first 980ti Hybrid, and 300 for the second after the 1080 launched.

Games that don't support SLI at all that I play is Subnautica, Skyforge, Arkham Knight, Ark, Playerunknown's Battlegrounds, and Yooka-Laylee. Most Unreal Engine 4 games currently do not support SLI, but Gears of War 4 just updated with SLI support, so there should be more UE4 titles that support it in the future. I do know that Just Cause 3 also doesn't support SLI.

 

The only game that I can currently think of that requires tweaking to support SLI is Tera Online. I'm sure there's more out there, but I haven't come across them since I really haven't been expanding my game library during the last couple years. Most of my time is going to League of Legends and PUBG. But with Tera, all you need to do is disable SSAO, switch the SLI bits to Max Payne 3, then you're good to go. If you want SSAO in Tera with SLI, just enable it through drivers.

That reeeeeeeeeeally depends on how you intend to play your games. 1080Ti SLI performs phenomenally well beyond 4k, which works for me because I prefer to use SSAA or DSR whenever possible to kill jaggies. But the lower you go from 4k, the less benefit there is to SLI-ing 2 1080Ti's.

So the games you play how are their framerates?

That's kind of a difficult question to answer, because I use non conventional settings for most of my games. I frequently use Reshade and/or SSAA with DSR. For example, I'm playing Tera Online at 5120x2880 with 4xSGSSAA and ReShade, and I'm playing GTA V at 5120x2880 with 4xMSAA. Regardless, I target 60 FPS minimum in all of my games, so I'd say the frame rates are pretty good.

 

Attached are the benchmark results of GTAV at 5k with 4xMSAA comparing SLI on and SLI off. There is an 87% gain with SLI on in these results.

So every game hits above 60fps right?

In GPU bound situations, yes.

[maartendc]

For me, any benefit you would get by saving money would be negated by the lack of support and stability of SLI.

 

Sure, on paper, 2 low-end cards in SLI might be cheaper AND perform better than 1 high-end card.

 

In practice however, if it is not properly supported by the game, (which often it isnt) you will end up with worse performance for your money than a single card.

 

Also, microstuttering has often been a problem with SLI setups. This means that even though you get 60 fps average, the first 50 frames might be delivered in 0.5 seconds, while the last 10 frames are delivered in the other 0.5 seconds. This causes choppy gameplay and stuttering, even thought the average FPS number looks good.  This has to do with the SLI cards not working together properly, or having to share memory bandwidth and such.

 

Also, you only get the amount of VRAM of 1 card, not both. So if you run 2 4GB cards in SLI, you only get 4GB, versus 1 high end card would have 8GB or more VRAM.

 

Personally I wouldnt do it.

 

The only reason I would get SLI, is if I already had a Titan Xp or 1080Ti, and I wanted more power. Then you can just add a second card in SLI.

[Mick Naughty]

I've seen stutter on a single powerful card. Atleast with the crappy 10 series. I'll stick to my old cards which run flawless and continue to out perform my new cards. I'm sure they won't last forever but until then I'll save my cash on more new cards.

As a long time multi GPU owner, I wholeheartedly disagree. IMHO, the only time SLI wouldn't be worth it is if the user doesn't configure their games appropriately to take advantage of the setup.

Configuration? Like what?

Use conductive resolutions (no 1080p with SLI 1080Ti), change multi GPU compatibility and rendering modes when necessary, etc.
