Is it true only MSI 3090 cards are the only ones you can use for SLI? thanks

And compute use but yea useless for gaming.It’s basically for benchmarking and world record over clocking. Not practical for gaming.
It takes time to implement it in any API. With DX9 and DX11, Nvidia assisted game developers directly. With DX12 mGPU, Nvidia straight up said that game developers are on their own - and that's why we have so very, very, very few DX12/Vulkan games that support mGPU.I am not the best at tech talk, but why ? wont they or anyone suppost it if it can double the power whats the problem?
Two cards doesn't magically double the power if the game isn't programmed to utilize two cards. Even then, even in the best scenarios, it doesn't scale 1:1 and it introduces other problems.I am not the best at tech talk, but why ? wont they or anyone suppost it if it can double the power whats the problem?
All the downsides of SLI have already been discussed to death. Funny enough we probably still have a few delusional people out there claiming SLI works great for them which is laughable. Even many AAA games flat out did not support multi gpu at all and nearly no smaller games did. And of the games that did there were numerus potential issues such as poor scaling, stutter, and flickering. And then a game or driver update could also bork multi gpu support. A few people get off on always chasing down fixes and workarounds so SLI was fine for them but now even Nvidia has seen how stupid it is to waste any more time on it.I am not the best at tech talk, but why ? wont they or anyone suppost it if it can double the power whats the problem?
Turn down settings , DLSS when available. Play at a lower resolution upscaled. Nvidia Control Panel allows you to create your own custom resolution, use DSR.Ok, but bad news is that single RTX 3090 OC to the MAX still handle about 90 fps on most AAA games. Optimized games like DOOM are only few of all.
Most of us like me planning to get 4K 120-144Hz monitors. We will stuck at 70-90 fps there.
Thank you, but why to get a big screen 4K Oled monitor when I need to reduce a lot of things ? Before that summer I have 2x Titan X Pascal and performance was abosilutelly the same like RTX 3090 so where is big improvement ?Turn down settings , DLSS when available.

The problem is more with what new games will effectively support SLI/mGPU, no use having it if the software does not use it. There are a few games like Shadow of the Tomb Raider, which is getting old now that is rather awesome for mGPU and not SLI. Besides there are many games that would exceed 120-144fps at 4K maxed out like older games and a number of newer games, just not all. Then again some of the settings can make a huge performance impact and have very little to no discernable quality difference. If you play all the older SLI titles, they should reasonably work well but then you probably in many cases would not need SLI with the 3090 anyways.Thank you, but why to get a big screen 4K Oled monitor when I need to reduce a lot of things ?

Can you provide a source for this comment? I have looked and cannot find a source claiming 3090 SLI DX11, DX10, or DX9 games are not supported. It would be really cool for someone to play The Witcher 3 at 4K on a 3090 SLI setup. If it worked you should get a constant 120 fps.Yep, Nvidia is officially never supporting SLI and the 3090 for gaming. Officially, no DX11 games at all via SLI profiles for the 30 series

Google, took me 20 seconds to find an article that covered it fully:Can you provide a source for this comment?

Yes it works for compute work loads for programs that support it. Which I believe most the major ones do. For gaming it is dead. Some people can't seem to understand that and just want to throw their money away.Does sli still work with video editing and 3d modelling software?
For some of those (most ?) you do not need an SLI/Crossfire setup it can use multiple card without having to be presented has if there was only one, i.e. multiple 3080 can work for video editing/CAD/Adobe encoding, SLI can be use to pool memory if your workload need more than the 24 GB of a 3090 too and not for the 3080.Does sli still work with video editing and 3d modelling software?

So depending on your work load it could be worth it to see if 2x3080 (or a lot of 2080) isn't better than a single 3090 for example.
After watching this video I see no point in buying 2 3090's for SLI gaming.
And just think only a couple months ago we had a person on here claiming that SLI has always worked great for them in every game. It's just hard to imagine that some people are that out of touch with reality and have deluded themselves that badly.
On planet “I got more money than I know what to do with.”I cannot believe people bought 2x 3090's for gaming. On what planet did that purchase make sense.
Did we watch the same video? Buy two then. You seem dead set on doing it.I saw that review last night it is not so bad actually. But I expected much more fps on SOTR for example.
I don't know what to tell you, you're living in a dream world if you think anything in that article made SLI worth it for gaming in nearly 2021.Ok, could you please read this final words ... https://www.build-gaming-computers.com/is-sli-worth-it.html
Makes sense - you do seem to enjoy spending extra for no reason.No, I will buy only one but OC to 450 Watts for better power bill. ;-)
Become most downvoted human on Reddit if you admit to SLI use
