Nice find, although it still concrete the 10 series not supporting  3 or 4 way right ?

No idea. Here is the latest info from Jacob...

Update:
 
More info about SLI support will be coming soon, please stay tuned.

maybe best way to think about it is, if nvidia used 3 1080s in the showroom (one being dedicated to physx) i think its a safe bet that 1080 will be restricted to 2 way, reason is that was perfect opportunity for nvidia to show case possibly 3-way sli with 4th being physx, being a booth of nvidia and all surely if 3 way was supported they have no issue bringing the 3rd card for tri sli as opposed to 2way+physx?  but they stuck to 2 way, maybe we can read into this as being an accidental way of confirming only 2way support?
 
or maybe im tripping nuts and over thinking this lol

Sounds right to me.

I bet to see quite a few green card fans to drop Nvidia this year, due to the Sli limitation, regardless of whether there is small gain beyond  2 way or not.  I have to admit, I'm just waiting for AMD to come up with something that is even slightly interesting and I won't feel bad at all to join the red team.

I have returned after a 2 year hiatus to participate in a soon-to-be epic thread.  This lack of 3/4 way SLI is disappointing.  For what it's worth Sajin, I knew exactly what you meant when I read the title.  I'm still rocking my 4 Titans on 7680x1440.  I really enjoy the performance of one card/screen.  Was looking forward to picking up 3 of these, but it looks like I will wait.
 
Oh and hey everyone:)

1080 supports 2,3 4 way SLi...the problem is that the HB bridge only works 2-way as of now - sacrificing any other card not getting any bandwidth - -
 
look at the bridge - a standard single sli bridge is 1/2 that size wide

 
HB bridge

 
Duh!! comes to mind here - - ie 4 way sli bridge.... in a 2 way config
makes for double bandwidth
 
that doesn't stop you from using a dedicated Physx or going double 2-way
 
if Nvidia was that concerned with bandwidth then make a NVlink connector for the cards or devise new SLI transit protocol..ie sli 2.0

This thread is now famous.

 
I have to admit that a few days ago when I first read the title of this thread, I didn't quite understand it either. So I PM'd Sajin, asked my questions, and got my answers. I was like, oh duh. LOL. I think i was reading to much into it, and started imagining other things or or something. I'm sure I wasn't the only one.     ;)

Nvlink is not for consumer cards, and is only planned for 2 super computers at this point. Notice how nvlink was all the rage, even after I posted numerous article shooting it down, and now... Not a peep.. No review sites, no you tubers, and hardly any forum members... Nvlink is a pipe dream for consumers for at least another year or two at absolutely minimum.. And I laugh at the people that believed they would get nvlink and be able to use 8 cards for gaming... That dream can officially Rest In Peace, especially since 3 cards aren't officially supported.

Also, you meant a the high bandwidth bridge resembles a 3 way bridge, since 4 way bridges are wired completely different than 2 way and 3 way bridges.
