I have already two dell up2715k
i am hunintg at ebay for third
so for now options are:
1. SoftTH
2. eyefinity6 card (but then I have to use old amd card - strongest card is W9000 which is 280x equivalent with 6gb ram - joke (i know i know, w9100 is better but cost a lot and already i have 2x gtx1080 so no point to buy that)
the biggerst joke is - gtx10xx series has DP1.4 which can run 8K @ 60hz but monitor have dp1.2 only, so to achieve 5K res both connectors have to be used
so maybe adapters, right?
Thundebolt3 @ 2x DP1.2 adapters are exist but simple DP1.4 to TB3 not, not even DP1.3 or 1.4 MST hubs
MASSIVE EDIT:
what do you think about - 3x ThunderboltEX 3 + 3x TB3 @ 2x DP1.2 adapters
should i get 5K each from one DP/TB3 from 1080?
edit2
in theory should work, but after i saw specs on this asus EX3 card - DP IN is in 1.2 revision
