I got 3-way & 4-way working in the game the witcher 3 using driver 372.54.

That is amazing sir.

The GTX 1080 still supports 3-way and 4-way SLI over the classic bridges that come with motherboards, but you would have to obtain a special software key from NVIDIA and would rely on your game/benchmark developers to optimize their apps for 3-way/4-way SLI. NVIDIA's regular driver updates will likely only optimize for 2-way SLI.  NVIDIA "Pascal" GPUs do support Microsoft DirectX 12's multi-display adapter (MDA) mode, but NVIDIA will not provide game-specific optimizations through driver updates for MDA. That would become the game developer's responsibility. The same applies to "explicit" LDA (linked display adapter).

SO, "Enthusiast Key" website --- Is where?
 
 
Enthusiasts wanting to use 3-way or 4-way SLI would download an app from an upcoming "Enthusiast Key" website, run the app, and generate a software key signature for their hardware to unlock 3-way and 4-way SLI in NVIDIA's Control Panel.

I got that in an email from hwbot this morning, it looks awesome. I might have to seriously look into picking one up. Thought you all might like to see it as well.

Not bad for $150, But the Shipping from Overseas to the US would be around $50.
 
I would want to wait until  they are available at a US retailer.

I'm hoping they will be. If they are I will be thinking really hard about getting one. I got a shipping quote of $39 though, so $189 total. Not terrible, but more than I'd want to pay right now.

And I Thought No One could get a Titan X Pascal 4-Way SLI setup to actually Scale properly in GAMES....

Hes most likely using a combination of older drivers, older sli profiles & nvidia inspector tweaks to get everything working. Looking forward to see what he has to say.

I knew they were using nvidia inspector to create custom sli profiles...

Wow, Even though those custom SLI profiles appear to solve the problem, That is a Lot of Work (Not to mention the equipment) in order to obtain good scaling in 4-way SLI Gaming with Pascal Series cards.
