Wow, if only every game had Strange Brigade scaling. 98% scaling is DAMN GOOD.
 
4K360FPS average @ Ultra Settings?
 
Sheet. Probably capable of 8K144.

I am planning to upgrade to EVGA G2 1300W within the next 12 months to do SLI. For now I can only afford one 3090 :D

Well, the good news is that RDR2 has Vulkan MGPU so that should work well. What surprised me in that video is that he (I guess Nvidia) says that BF1 also works with DX12 MGPU? Why on earth would they not implement it in BFV then?
 
Anyway, definitely going 3090 SLI - if I can find them in stock that is.
 
Here's Strange Brigade with Titan RTX SLI @ 4K maxed (~ 225fps):

If a game played used it and could bench with sli.. yeah thet would be enough for me to justify it.

Sell the other off when I'm not using sli anymore though.

The PSU requirements alone make it a non starter for me.  I would need something like an EVGA 1600w unit which would require the circuit in my office to be upgrade to 20A.  Being that it's on the second floor, I would have to rip out the existing wiring and redo the walls.  Not sure $3k+ is worth SLI in Strange Brigade :)

It sounds like a better option in your case would be to use dual power supplies and put them on different branch circuits (i.e. breakers) in your office.
 
Also, sometimes the wiring itself is rated for higher current than either/or the outlet or breaker. Meaning that possibly an electrician could replace the receptacle and/or the breaker to the 20 amp version(s) and you'd be set. It'd be MUCH cheaper than needing to pull new wire which will likely mean opening up the walls.

Since it’s a feature baked into DX12/Vulkan and supports both nvidia and AMD out of the box, I actually expect more developers to start implementing it.

Wishful thinking. Plenty of dx12 games that don’t support mgpu. Developers are lazy.

They always were, even when SLI got first introduced. At least it might motivate them a little now that people can just mix and match any GPU.

I for one not going to sell my 2080 Super now. I am planning to use it as a Plex encoder as soon as I upgrade my PSU to handle the 3090 and the 2080 Super.

I expect a not so bad multi GPU performance in games that support it!

SLI was a big thing back in the day when Voodoo cards came out because there was a substantial improvement in running two (or more) and jumping from 20 fps to 40+ fps, but there's little reason to run multiple GPUs nowadays. A single graphics card is often more than sufficient to run games over 100fps with enough eye-candy to keep the majority of gamers happy.
 
Also, DX12 has been out a while and multi-GPU support would have already made a difference if it was going to. So, despite how cool it sounded in theory, the reality is that most gamers have been perfectly happy with a single GPU and I don't see that suddenly changing now, especially given that graphics cards will be super competitive by the end of the year and consumers will have a lot of choices, all of which run 4k perfectly fine. Also, given that both AMD and Nvidia are trying to reduce draw latency, multi-GPU support in DX12 probably hinders that goal more than it improves framerates. 
 
Plus, I think there are a fair number of consumers who are fed up with SLI and would prefer a single high-end card over multiple low/mid-range cards. Personally, I'm more concerned with my overall experience than with price, so a single 3090 that works in all games is a better deal than multiple cheap cards that exceed it in theory but don't work in most games. 

SLI is dead. You notice it was dropped completely on the 2XXX series?

Yea no argument here. In the slightest. Putting the burden on game makers to support an extreamly small portion of there audience means it is gone.
