Are 3 GTX 970s needed for a triple monitor GSync setup?

I currently own an Asus GTX 970. I want to scale up to a multiple monitor build. Something like 3 Asus ROG Swifts. Do I need to have 3 GTX 970s in SLI to take advantage of GSync? Because GSync only works with Display Port and each GTX 970 only has one. If yes, wouldn't it be better to switch the existing 970 with a 980, as that comes with 3 Display ports?
 
Solution
I would be hesitant to experiment with a triple SLI set up with the known memory issue on the GTX970. Especially on 3 monitors. From what I understand (last I checked which was several months ago) anything over 3.5GB of memory consumption can potentially lead to performance issues.

But, no, I can't answer your question with Gsync and SLI as I have not familiarized myself with that configuration yet.

Thanks anyway. Let's say I settled go for a dual SLI 970 setup. I'd have 2 Display ports and an HDMI 2.0 port. Would that be sufficient to run games at 1080 x 5760 at the least? And will the screen tear be a huge deterrent, considering I won't get Gsync on the HDMI port?

You can overclock your GTX 970 to match the power of a GTX 980. If you get two GTX 970's and overclock them to match the power of a GTX 980 sli config, you will easily run mot games at about 50 FPS. 4k has four times as many pixels as 1080p, so with triple 1080p monitors your GPUs will need 0.75 times as much power as 4k, and that's well over 60 FPS (the most common monitor refresh rate) in any game except very graphically demanding games that don't even support SLI such as Crysis. You can also throw in MFAA for no-FPS-cost 2x MSAA. But don't worry about the numbers, your system will kick arse any way you put it.
