In theory, if we could get anywhere close to 100% utilization on both GPUs, we would probably see the 3090s in SLI outperform the 4090 by a good margin

In reality we'd see $2000+ of video cards performing higher than ~$1600 of video card while lacking support for DLSS 3.0.

Sounds like bull to me. In reality (having just bought a 3090 this month) you can get three 3090's cheaper than one 4090 currently. If SLI scaled well and wasn't such a mess around, I'd definitely consider a second.

In Port Royal, my SLI 3090s still beat a 4090, with the exception of the world top overclockers using LN2 to cool a 4090. I'm getting 31,000-32,000 scores in Port Royal. However, for gaming, the 4090 is faster because very few games support SLI with 3090s.

One of the main reasons SLI is dead is the person at Nvidia that ran and promoted SLI left the company. Very few games support Explicit Multi GPU in DX12 even though its easy to implement.
