When going SLI the lower clock of the reference card won't matter, they'd be fast enough – to put it mildly – for every game anyway. And the reference cooler might really be a good thing in such a setup. On the other hand, there will be aftermarket cards with coolers like this as well – I think I even saw a MSI card which combined such a cooler with a second liquid cooler? Yes, the Sea Hawk: https://msi.com/Graphics-card/GeForce-GTX-1080-SEA-HAWK.html#hero-overview https://msi.com/Graphics-card/GeForce-GTX-1080-SEA-HAWK.html... – of course idle speculation without reviews, but something like this could be cool for you. I don't think the aftermarket cards are month away. A german vendor was listing some versions yesterday as 3-10 days away. I think that could be accurate, the listings on the vendors sites are all ready. I would recommend to do it stepwise. One card with two displays, look how it performs, then add one or two displays more and maybe the second 1080, if needed – I don't know which game one would play on more than one 4K displays, and to play on one 4K display one 1080 would be fine. Don't think I have to explain here that this is still a pretty crazy setup, do I? ;)
