I'm unimpressed. Shadow of Mordor and Battlefield scale well, but we're still seeing games where the scaling brings only a 30%-40% improvement, and apparently many recent releases didn't see any improvements at all. Unless nVidia step their game up, I'm very wary of buying into SLI again for performance improvements that don't come close to the cost of buying another card.
If the second card cost 30% as much as the first, it would seem much more reasonable. But they don't.

In my opinion for all the new games we play at the moment in 3D vision - with or without fixes -, the 980Ti or the Titan X are just fine for ultra settings. So, I am absolutely not impressed by the 1080. It might be considerable to purchase a Titan X2 or a TI version for of the 1000er generation in one or two years, when the new consoles drop.

I could never get SLI to scale properly with games benchmarks were no problem. This is one of the reasons I will always purchase the best video card for a single card solution.
Benchmarks are written with SLI in mind where games are driver depended on SLI profiles.
When it works it great.

I sympathise Pirateguybrush. I'm pretty sure that the problem isn't SLi scaling but a CPU bottleneck. In 3D Vision, you can double those resolutions but I remember you saying that you are only coming from 1080p or 720p on projector, which may make the exercise less fruitful on your system.
For what it's worth, I got SLi working with Oculus Rift, even though it's coded to be disabled by oculus.
Still experimenting when I have the time but I patched the pixel clock and used some stupidly high resolutions, and SLi started working on VorpX all of a sudden... at 5am. Then I had to get some sleep. Perhaps it was a hallucination :P , I'll need to investigate more tonight.
SLi should be huge improvement for VR. Certainly, I didn't notice any lag (the reason behind disabling SLi according to Oculus) and I haven't benchmarked to see if there was a performance difference, but both cards were working when before only one would.
bo3b and I have a little discussion going on over at the VorpX thread over here, where I'm trying to use some of his sage advice to supersample on the rift: https://forums.geforce.com/default/topic/939564/3d-vision/have-any-of-you-tried-vorpx-/
I'm having to hack to some crazy custom resolutions: Last night I got 4320x2400@120Hz to "work", according to bo3b I need 6344x3172 @ 90Hz for perfect 2:1 supersampling on the rift.

I'm especiallly frustrated with the poor sli scaling on Rise of the tomb raider (i know about the sli bits alternative but flickering is bad and performance gain is almost non existent)

Hmm... I think I posted in a different thread but I have almost zero issues with SLI scaling in 3D Surround.
Sure for some is better while others not so great but I always managed to get SLI to work and give extra FPS.
Regarding to ROTTR and alternative SLI bits, the only flickering I've seen is that of some snow decals and that is SOOO remotely visible (around 5% of the full playthrough, that I consider it not worth even mentioning it)...
The day SLI will stop working is the day I will not buy GPUs and give up on gaming altogether...
I think people expect too much "out of the box" these days...sadly:( (The real problem is things got complicated very fast and the "generilistic" solution starts to show it's weaknesses...
I always said PC gaming is about tinkering with stuff... If you want problem free solutions go with a Console...oh wait... even there are problems...
SLI is a very complicated thing - once you understand how it actually works - and I am amazed it works so good as it currently does...)
