Will drives like 960 evo or pro bottleneck if it is ran through Z370's PCH ? The Z370 PCH has a DMI link of X4 between the CPU. If two GPUs are in X8 X8 (from CPU) then remaining components like NVMe SSDs need to go through one X4 interface right ? That way will the NVMe drives be able to reach its full advertised speeds or will it bottleneck ?

Thanks

The current Samsung 960 series, Evo and Pro, will not be bottlenecked. M.2 slots utilize PCIE X4 and provide enough bandwidth. There is only ever an issue when some boards share bandwidth between a PCIE X16/X8 slot and the on board M.2.
