DisplayPort 1.3 and HDMI 2.0b, with HDR support  and support for 1080p and 1440p displays at 240Hz, ultra-wide 1440p displays at 190Hz and 4K displays at up to 120Hz
 
NVIDIA is also stating that display port 1.4 will be supported as well since that version is just a VESA Display Stream Compression change (which also allows 8K monitor support with 60 hertz).

If they support DP 1.4, they're also supporting FreeSync which is in the spec?

That's interesting Brad because I thought that DP 1.4 was simply a compression change for 8K.

Ah, you're right. DisplayPort 1.2a is FreeSync, not 1.4.

Wikipedia DP1.4 specs:
[DSC is a "visually lossless" encoding technique with up to 3:1 compression ratio.[20] Using DSC with HBR3 transmission rates, DisplayPort 1.4 can support 8K UHD (7680×4320) at 60 Hz with 10-bit color and HDR, or 4K UHD (3840×2160) at 120 Hz with 10-bit color and HDR. 4K at 60 Hz with 10-bit color and HDR can be achieved without the need for DSC. On displays which do not support DSC, the maximum limits are unchanged from DisplayPort 1.3 (4K 120 Hz, 5K 60 Hz, 8K 30 Hz).[22] ]

But wouldnt they still support freesynch? Can you support 1.4 and not 1.2a?

My interest is to see when EVGA plans on bringing out a hydro copper version. Thats what im waiting for. 

I have a question that I can't seem to get an answer too.  If its been asked and answered I apologize.  Do these new cards have stackable memory?  My take is that this means two 4 gig cards in sli would actually be 8 gigs of memory.  any hoo sorry if it sounds stupid. 

Of course as soon as I post this I find the answer.

with pascal we have unified memory - so an 2 gtx 1080 8GB cards will give you 16GB of ram in SLI not the standard of one card's memory regardless of how many cards you used to have in Sli
