Hi. I have a 690 GTX. I'm not sure if a second 690 would boost performance in SLI for 3D Vision? I guess this would be considered quad sli. I'm not even sure if quad sli profiles exist for 3D Vision. Does anyone know? I'm also not interested in newer games. Mainly games that were released in 2012 or earlier. Thanks.

Short - Nop.
Since 3-way SLI didn`t work at all then I`m guessing quad is even worse. Also remember that Nvidia gave up on 3-way and 4-way SLI for mainstream market so no support for that in the future as well.

Quad SLi and 3d vision still works for now. But probably not for much longer and certainly not at present if you are using Pascal generation cards.
I first started using quad Geforce 580 cards, then upgraded to evga sc quad 780 ti's and then changed to quad 980 ti's. However for the 980 ti's I stepped back to 2-way sli as gaming g1 gigabyte cards and MSI 980 ti's were running hot when cards sat next to one another. I was waiting to watercool all 4 cards but never got the chance.
I am running 3d vision surround, currently with a i7 4960x with 5760 by 1080 resolution. 3d vision surround rocks. I have used the occulus rift I purchased for about 3-4 hours on the day it arrived but have not touched it since. Overall I was disappointed with the poor FOV and resolution and also noticed I would get uncomfortably hot after an hour with the headset on.
I know the argument of diminishing returns but as I am aiming for solid 60fps in 3d vision surround with high settings+ I was willing to use quad sli to achieve this. However with the 980ti's I can happily gaming with very high settings in 3d surround with 2 cards so I think when the 1080 ti's come out 2 cards should be fine for 5760 by 1080 resolution at least. However it still sucks that Nvidia is limiting Pc consumer choices to vanilla sli. Triple or quad sli apparently will not even configure with the geforce 1080's and quad sli bridge and will limit sli to only 2 cards from what I have read.
I think there is still a bug in the 3D vision drivers when it comes to triple screen setups and I get more than 1/2 fps drop switching from 2d to 3d and compatability mode is disproportionately faster than real 3d. Games like mad max run at 60fps on very high to ultra settings in real 3d thanks to the community fix, but for alot of the games like Witcher 3, Fallout 4 I am using compatability mode which looks better in surround that in single screen compatability mode in my opinion anyway.

At first they said you could get an "Enthusiast key" and enable an experiental form of quad SLI going forward but have since done a 180 on this.
I think 4 way has always been a bit dubious, you are better to get 2 SLI of the best cards you can afford.
As for 3d surround, I think it's pretty game specific and depends on what resolution you are running. Its out of the question for me at this point with 1440p 3d surround as I want high settings at 60fps above all else

Yeah, like necro said.
Depends on the resolution of each panel. 1080p x3 is doable with 2xSLI.
Even so, if you plan to play Witcher 3 for example in 3D Vision (geometry 3D - not CM mode) you will have trouble achieving 60 FPS. You'll get around 40FPS on 2x980Ti overclocked. Probably on 2xGTX1080 you will be able to maintain a good 60FPS at 3x1080p displays.
In other older games you will have little trouble keeping 60fps at 5760x1080.
Now if you increase the panel resolution the GPU requirements will go UP exponentially (they aren't exactly linear as we all know).
It's all about finding an equilibrium between GPU power, number, panel size and game/engine settings;)
You will also need a MOBO with fast 16x PCI-E lanes when running in SLI. (Most mobos will downclock the lanes to 8x in SLI).
While I've seen 3xSLI work better in 3D Vision Surround than 2D Surround and single screen I am not yet sure if the benefits are another 50% from a single GPU like is in the case with 2xSLI. I haven't test it personally cause I find it too demanding (Mobo, Case, PSU, Waterblocks etc), but 2xSLI I have and I can say in 90% of the games you get the 50%+ benefit from a single GPU.

I say go for it and buy yourself 4-way SLI - just to troll you and laugh after. Remember thou that someone at this forum told you that it doesn`t work and that means you won`t get any performance increase compare to 2-way sli.

I tried this exact experiment awhile back, two GTX 690 cards for quad SLI.
While it 'works' in the sense that nothing bad happens, and you can enable the cards, I measured the performance and did not see any scaling at all in most I tried, and negative scaling in others. The special scenario of Metro LL did have 4 way scaling however.
I don't think I ever finished my research on this because one of my ebay cards had a bad GPU that would overheat. Best results I posted: https://forums.geforce.com/default/topic/825934/3-way-sli-is-it-pointless-/
The short story was that it worked in a couple of games, and actually broke a couple of games. A mixed bag.
However, the big caveat there is I could have been CPU bound on some tests, and thus no further scaling is found. I did not test Surround because I'm not setup with it.
Given the price of a GTX 690 at this point, if you desire to run Surround, it's probably worth the time and expense to experiment with it. If you are doing single screen, I don't think there is any value to it.

If you are talking about single screen 3d I'd say sell it and upgrade to a 10 series but I still have quad sli 690's running in a 2nd pc made of of my spare parts that I keep on win7 to play mainly the "legacy" dx9 games in 3d vision surround. The best way to get the most out of them I found (wish I could remember the original source I got this from) was to use a .bat file + nvidiaInspector.exe to lock in an overclock and keep the clocks from randomly throttling down. With that I can run them at a steady 1150mhz and run most dx9 games that stay under the 2gb memory limit at 60+ fps in 3x 1080p 3d vision surround vs. usually 30-50fps on just 1 690. Just to quickly test that again I checked the opening of BFBC2 single player and got around 40fps on 1 690 and 70fps on 2 with quad sli enabled for 5760x1080 in 3d.
