well here how I see 3way and 4way over 2way sli ........ for the one's that can't afford to do 3 and 4way, do to the coast. I have found that they don't want rest of us that have the mean to buy the cards to do 3way and 4way. so that are computers are no faster thin theirs.  so my point would be go work harder and quit doing on daddy's money and do on your own like me and some other do . my last build took 2 years to build do to coast but I love doing it and I will do it again lol and big smiles. and just to say I have mine the way I wanted it . there are a hole lot of great computers out there better than mine and some not but I build for me just like u do for u and if someone like's 4way thin sobe it. it's their cash.

It's not all about the "money", but the results. Many point out that the scaling is not really high or much gain going from 2 cards to 3. That is why so many are skeptical and hesitant on doing it. However, there are other areas that they could look at to justify on going 3 way. 4 way, meh... if you're into benchmarking, fine, and honestly to me would be the only reason to do 4 way SLI and/or folding and other programs. Money is not always the factor, nor is Dad. Just saying... based on your paragraph.

Indeed, I will be eagerly awaiting the news.  Just a couple more days and we will know what the heck is going on.  From the video that was linked, it appears that 3 and 4 may be supported after all.  I'm really hoping that's the case.

It will support more than SLI.

Jayztwocents has already said it supports more than 2 way SLI and nvidia has already agreed to send him 3 cards for 3 way SLI benchmarking. Plus everyone is taking what was said out of context. The only thing that was said was that at the moment the HB Bridge only supports 2 way SLI.

Yup, that is what I gathered as well from watching the video.

Other SLI adapters shown. Also will add if we do see a GTX 1080 TI, it will be smaller and have HBM2 to compete against Vega.

I'm going to be a troll now. I think that guy is a dweeb. I don't listen to anything he has to say, and there are other sites available which have the same information that he provides, whom provide it in a much more simplified way. If I wanted technicality, I'll read a book, not a youtube video.

ugh.. really NVidia. some on switch...
For this class of user we have developed an Enthusiast Key that can be downloaded off of NVIDIA’s website and loaded into an individual’s GPU. This process involves:
1.Run an app locally to generate a signature for your GPU
2.Request an Enthusiast Key from an upcoming NVIDIA Enthusiast Key website
3.Download your key
4.Install your key to unlock the 3 and 4-way function

Basically out of box it supports 2-way, if you have 3-way you have to go to nvidia site and ask for a enthusiast key which will unlock 3-4 way sli in your bios. seems.... unnecessary and I don't see the reason why.

Well at least you can still do it. Why would they do this though? Trying to figure out how many people actually use 3 & 4-way sli?

Good question.  If they aren't CHARGING for it, why do it at all? Hopefully we aren't on the road to "K" like unlocked cards ala Intel.

That would suck.
 
My main question is...
 
Are 3-way & 4-way going to be getting maximum performance optimizations or is going to be limited to sli?

Limited to SLI for DX12.  The video linked above explains pretty well, BUT this article does an even better job:
 
http://www.guru3d.com/articles-pages/nvidia-geforce-gtx-1080-review,4.html
 
Scroll down to "New Multi GPU Modes".  
 
Basically, it boils down to this:  Nvidia will only officially be optimizing for 2 cards in SLI.  It's up to the developer to optimize for 3 and 4 way systems.  As someone who games in surround at 7680x1440p, I have my doubts that 2 cards will be able to maintain the framerates I would be happy with.

Well at least you can still do it. Why would they do this though? Trying to figure out how many people actually use 3 & 4-way sli?




Good question.  If they aren't CHARGING for it, why do it at all? Hopefully we aren't on the road to "K" like unlocked cards ala Intel.


That would suck.
 
My main question is...
 
Are 3-way & 4-way going to be getting maximum performance optimizations or is going to be limited to sli?


 
Limited to SLI for DX12.  The video linked above explains pretty well, BUT this article does an even better job:

Scroll down to "New Multi GPU Modes".  
 
Basically, it boils down to this:  Nvidia will only officially be optimizing for 2 cards in SLI.  It's up to the developer to optimize for 3 and 4 way systems.  As someone who games in surround at 7680x1440p, I have my doubts that 2 cards will be able to maintain the framerates I would be happy with.


Well that sucks. 






Bottom line... you're limited to sli in dx12 unless the game/application developer supports 3 & 4-way as nvidia isn't doing optimizations for 3 & 4-way anymore unless you're running in dx11.

New Multi GPU Modes

Compared to prior DirectX APIs, Microsoft has made a number of changes that impact multi-GPU functionality in DirectX 12. At the highest level, there are two basic options for developers to use multi-GPU on NVIDIA hardware in DX12: Multi Display Adapter (MDA) Mode, and Linked Display Adapter (LDA) mode. LDA Mode has two forms: Implicit LDA Mode which NVIDIA uses for SLI, and Explicit LDA Mode where game developers handle much of the responsibility needed for multi-GPU operation to work successfully. MDA and LDA Explicit Mode were developed to give game developers more control. The following table summarizes the three modes supported on NVIDIA GPUs:
  

 
In LDA Mode, each GPU’s memory can be linked together to appear as one large pool of memory to the developer (although there are certain corner case exceptions regarding peer-to-peer memory); however, there is a performance penalty if the data needed resides in the other GPU’s memory, since the memory is accessed through inter-GPU peer-to-peer communication (like PCIe). In MDA Mode, each GPU’s memory is allocated independently of the other GPU: each GPU cannot directly access the other’s memory. LDA is intended for multi-GPU systems that have GPUs that are similar to each other, while MDA Mode has fewer restrictions—discrete GPUs can be paired with integrated GPUs, or with discrete GPUs from another manufacturer—but MDA Mode requires the developer to more carefully manage all of the operations that are needed for the GPUs to communicate with each other. By default, GeForce GTX 1080 SLI supports up to two GPUs. 3-Way and 4-Way SLI modes are no longer recommended. As games have evolved, it is becoming increasingly difficult for these SLI modes to provide beneficial performance scaling for end users. For instance, many games become bottlenecked by the CPU when running 3-Way and 4-Way SLI, and games are increasingly using techniques that make it very difficult to extract frame-to-frame parallelism. Of course, systems will still be built targeting other Multi-GPU software models including:
  • MDA or LDA Explicit targeted
  • 2 Way SLI + dedicated PhysX GPU

Wait Just A Minute... So No More 3 & 4-Way SLI?

Correct, NVIDIA no longer recommends 3 or 4 way systems for SLI and places its focus on 2-way SLI only. However, for those of you that do want more than two GPUs, there is a way (albeit complex). However... meet the enthusiast key. While NVIDIA no longer recommends 3 or 4 way systems for SLI, they know that true enthusiasts will not be swayed and in fact some games will continue to deliver great scaling beyond two GPUs. For this class of user they have developed an Enthusiast Key that can be downloaded off of NVIDIA’s website and loaded into an individual’s GPU. This process involves:
  1. Run an app locally to generate a signature for your GPU
  2. Request an Enthusiast Key from an upcoming NVIDIA Enthusiast Key website
  3. Download your key
  4. Install your key to unlock the 3 and 4-way function
Full details on the process are available on the NVIDIA Enthusiast Key website, which will be available at the time GeForce GTX 1080 GPUs are available in users’ hands."
