hi , i am thinking on purchasing Asus Z270-A motherboard , it has 2 m.2 sockets on it , i want to install 2 Samsung 960 EVO NVME m.2 on it , but im not sure if it will work , on the manual it says tha 1 socked is dedicated for m.2 (SATA and PCIE) and the other one for PCIE only , im confused as i dont know much about the difference between m.2 drives, also im planing to put an i5 6600k processor on it and GTX 1070. any help would be apreciated
