Furthermore, with USB-C 3.1 the bandwidth is limited to 10Gbit, which is why you have to consider which monitors can be connected. For 4k at 60Hz, Thunderbolt is clearly recommended, as 12.5Gbit bandwidth is required for 4k 60Hz. 4k at 30Hz is possible via USB-C 3.1, as only half of 6.2Gbit is required, but 30Hz is not recommended...
