Witcher 3 is a bit hard to run consistantly. I could run some benchmarks if you like - if I remember I hope that Ryzen and the 6900K see better utilisation soon because it seems to be high performance CPU support that's dying or dead at the moment, not SLI.

If you are going to do any testing at 1440p - even if it's ultrawide - use DSR to really make sure the GPU is your limiting factor otherwise you, like TTL, could come to the very wrong conclusion that some games and the driver support SLI entirely at high resolution, but don't support it at low res >_< OC3D found this (though didn't have the sense to correctly interpret their own data >_>) whereby they found that even on a very good CPU they were only GPU bound by a single 1080 Ti enough to get any benefit from a second one at 4K. There are other problems with your testing idea, which is that there is massive disparity between GPU power and CPU power at the moment. There's no evidence SLI is being abandoned at all, and even if it were using old games like GTA V and The Witcher 3 with well documented SLI support along with synthetic benchmarks would not reveal this. You'll find more results and they are pretty much the same thing. Anyone have two 1080 TIs in SLI that is willing to share their Witcher 3, GTA 5, and Firestrike benchmarks with me? Two 980 TIs still outperform a single 1080 TI by about 7-9% or so, however, that is not nearly a fair comparison. It would be interesting to know how far SLI is being abandoned as a concept. I truly can't find ANY (not even one) benchmark comparison of two 980 TIs in SLI vs two 1080 TIs in SLI using a 3440x1440 monitor (so not quite 1440P, and not quite 4K).

I know this topic has been beaten with a dead horse, but hear me out.
