Hi. I dont quite understand the foundation of how these two operate. First off i have an Asus Prime Z370-A mobo. My current OS is on an HDD and I am moving to an M.2 drive. I need clarification on how the PCIE lanes work. I have a discrete GPU connected on the first slow Gen 3 x16. Would having an M.2 impact the speed of the GPU in any way, and vice versa?
