I can promise you a 1080 SLI will not perform as well as a 3080 lol

Saying SLI is dead is like saying multi-core is dead because games don't benefit much from it anymore. Lol.
 
If it was dead, 3090 wouldn't be SLI-ready. SLI is still very much alive and kicking.
 
Two 3090's in SLI is pretty much the only upgrade path for 2080 Ti SLI owners.

I've got 2x 1080 FTWs at the moment, which have served me well for many years.

Looking through all the threads on here, it looks like a 3080 is about the same as a fully overclocked 2080 Ti. We won't know until the proper benchmarks are out, but it's roughly about right.

Here's a thread with benchmarks for a 2080 Ti FTW3 Ultra Hybrid - https://forums.evga.com/H...-Kingpin-m2948685.aspx - The Fire Strike Extreme score that's linked in there is 18897.

Here's mine - https://www.3dmark.com/3dm/50231291? - 18898.

I know there's RTX and DLSS, but ignoring that, assuming that SLI is present in any games, the rough performance of a brand new £700 3080 is going to be the same as my current setup.

I've been out of gaming for a little while, and it seems that fewer and fewer games support SLI. What's the latest - what percentage of AAA releases are supporting SLI at the moment?

I sold my RTX 2080Ti around 3 weeks ago and got £850 for it (not bad considering they are now going for £550). I sold it purely so i could get a RTX 3080 or 3090 because those new cards have HDMI 2.1 on them (which will connect to my HDMI 2.1 TV with full bandwidth). The RTX 2080Ti only HDMI 2.0 with 18Gbps bandwidth so i was only able to do 4k 60hz or 1440p 120hz.

With the RTX 3080/90 and its proper 48Gbps HDMI 2.1 connection, i'll be able to do 4K 120hz. And as we saw from the Doom Eternal benchmark, the 3080 gets around 90-130 FPS at 4K on ultra setting. Which is well in the 40-120 FPS G-sync range of my TV. So there are reasons to buy these cards other than just for performance. They provide better compatibility with new tech. Asus announced last month that they will be bringing out a new line of HDMI 2.1 monitors in time for the Holiday season.

As for SLI, it seems stupid to have it on the 3090 (which doesn't need more horse power) and not have it on the cards below it (which would benefit from more horse power). I've seen plenty of games which do support SLI. And if they don't support it right away, usually after about a month or so, an SLI profile pops up and the games become SLI-ready. Being able to SLI two RTX 3070's would have made so much sense. But whatever, just buy a 3080 and you'll have enough performance anyway I suppose 

I'd say a 3080 would be better than 1080 SLI, even if it's a side-grade on 3Dmark, most everything else won't get the same yield that 3Dmark does from SLI, so it'd be a clear winner in almost anything else. (I'm going from 1080 ti SLI to a 3080, even if there might be a bit of a loss in stuff that has very good SLI scaling)
 
I don't think SLI is dead however, but support has been dropping, from limiting 3 and 4-way SLI to just benchmark programs with the 10 series, to 2 way only with the 20 series, to only on the very top of the line card with the 30 series instances of SLI are decreasing, but not gone yet. If it'll flatten out or even climb back isn't something I know, but I could see it as possible that SLI will keep getting more and more limited in where and how you can get it.

I started with 2080ti sli but honestly i had to back catalog games to even use it.
Modern games are not even supporting it. When metro came out and only supported single gpu that was the last straw for me

SLI might perform good in 3D Mark, but that is it. In 90% of the games it doesn't do anything anymore.
I used SLI the last time with the GTX 680 and it was OK, but after that I just used single GPU and didn't feel the need for a second one ever again.
 
If you want the best performance, just buy the 3090. I will go with the 3080, because I think the 3090 isn't worth $1499 for some extra performance. But that decision has to be made by yourself.

If it were alive and well then it would be available on more than just the 3090. While not all encompassing, less than 1% of people use a 2080 Ti according to Steam's hardware survey. I suspect the 3090 will be around the same after 2 years. If developers have to support SLI in their titles then we'd want a wider amount of enabled hardware, not less.
 
 

Glad im not buying atm.. 10gb with the 3080 seems too low. The 3090 with its 24gb ram would seem overkill but it's what I'd be leaning.. then ya know a card released in the middle would happen eventually.

Sli? Naw. Just take that money you would be using to buy 2 cards and just buy the 3090.. has sli if ya ever need to later on.

AHowes

Exactly - I agree with every point in this post.

SLI is virtually useless for gaming and has been for some time now. As a multi GPU enthusiast and former overclocker it is however still alive in the benchmark arena. The support for SLI in games has been steadily declining for years now. Most game developers, even triple A studios don't bother with it for their games. Sure there are a handful of games that use it and of those handful some even use SLI very well (Sniper Elite 4 and the Asura engine come to mind) but is that worth the price of a second $1500 GPU to you? A handful of games with spotty support and scaling ratio that isn't anywhere near the 2x cost ratio you had to spend to use it? 

I still want a 2080 Ti SLI setup to OC on, if nothing else.

would 3090 sli even work on my motherboard I am running rampage vi extreme on X299 I notice the nvidia founders cards are triple slots I will be buying 3090 sli but I am not decided on if I want to get evga FTW models or the nvidia founders if the evga ftw models are only 2.5 slots I could consider that I know gigabyte has a 3090 the trinity I believe that is only 2.5 slots.

One would want blocks on sli cards.. but that might just be me.
