SLI in 2019?

as per the title, I have the chance to buy another 1080ti at a decent price.
Currently use is 1080p 144hz but looking to move to one of the high hz 4K screens.

Would it be worth it and running it in SLI or would I see no really gain?
 
I haven't used in SLI in years but whenever I read anything about it these days, the general consensus seems to be that it isn't worth it (multi-GPU in general).
 
There was an identical card to mine for sale in the MM, so I googled around on SLI.

Made for depressing reading.

Single card seems to be the future.
 
SLI for 2019 is a waste of time as there is very little support for it.

My guess is in the future mGPU will make a comeback as manufacturers will be forced down this route but that is quite a few years away and no use for anyone considering 1080 Ti SLI.

In short stick with a single card.

If you really want more performance sell you 1080 Ti and get a 2080 Ti but that is very bad value for money.

Shame really as from what I read 4k is still hard resolution to get some games playing at ultra at 60fps or even high refresh monitors.

SOTTR
2160p maxed
Single RTX Titan stock

Ray Tracing on

Ray Tracing off

Fortunately SOTTR is one of the few games that runs SLI well and really helps with the fps.

50% penalty for RT, nice. Might look pretty but whats the point. Does SOTT use DLSS?

You can use DLSS in SOTTR.

RT does not add much to SOTTR and I suspect that lots of people would struggle to tell if it was on or off when gaming, me included.

I suspect this will be the case with a lot of stuff, not just SOTTR, at least for the foreseeable future. I guess it's the only way for the tech to develop and become more mainstream though, guess only time will tell.
 
You must have SSAA turned on to get those low frames there. Don't use SSAA it's crippling even in Tomb Raider 1. DLSS and FXAA and you're raytracing ultra at 60fps.
 
I only posted those benches to show what using max settings do to fps.:)

I am off to play Baldur's Gate 2 now which looks quite nice @2160p even though it has hardly any graphics options and is so old I don't even know what API it uses lol.:D

One of the things SLI used to be good for - if you couldn't get direct scaling from it you could use SLI AA which generally did share the AA workload - but at 4K that isn't always useful and/or well supported these days last I checked.

Hell yes! Having recently binged on Thronebreaker I remember how awesome these old school rpgs still are. Shame to see a GPU be unutilised but it's just a tool at the end of the day.
 
I tried to revisit them recently BG1 and 2 although it was cool the nostalgia was keeping it going it is too dated to enjoy it like back in the day.

I've been running 1080ti SLI for a couple of years and I'd say its definitely worth it if the games you play support SLI or most of them do.
In Tomb raider, the Witcher 3, GTA 5 and even Arma 3 the results with SLI are very noticeably better for me. Much faster frames and or higher
settings. Dirt Rally 2 is an annoying example of a recent game with no SLI profile yet so I'd check which games you play that are supported first. I also play World of Warships which doesn't support SLI but using AFR in Nvidia control panel lets SLI work well.
If you want better than 2080ti performance for reasonable money its a good solution imho.
I don't really understand why there is a consensus SLI is dead, I guess because Nvidia take so long to support certain games whereas others get a new profile soon after release. I'm on a 5960x at 4.5ghz.

I missed the 1080p 144hz bit as I'm at 4K 60hz but I see significant gains. No idea about frame times as I imagine that's important for you. SLI AA looks beautiful at night in Arma 3 btw.
