If you just want the displays, you can get that over vanilla USB-C: https://www.cablematters.com/pc-1220-126-usb-c-triple-4k-displayport-mst-hub-usb-c-to-displayport-splitter-with-dual-displayport-and-hdmi-for-windows.aspx https://www.cablematters.com/pc-1220-126-usb-c-triple-4k-dis... If you want displays and all your other dock stuff combined under a single cable, that's where you're better off with Thunderbolt, yes. The USB-C docks can do some of this (I think with DisplayLink) but not quite as well. A Thunderbolt dock doesn't limit your display choices like the comment I replied to was talking about though, you'd just use any normal DisplayPort screen. Worst case without it you're plugging in separate display cables in addition to a non-video USB hub.
