Hey, this is a topic im very confused about. How the hell do the PCIe lanes work on amd ryzen.
Im planning to upgrade to a Ryzen 7 2700X with a B450 Tomahawk MAX motherboard. I use 3 drives ( 2 sata SSD's and 1 HDD).
I also want to use two gpu's. an RX 580 for gaming and a gtx950 for computing.
Ryzen 7 2700x has 20PCIe lanes, which would allow me to use 2x8 for the GPU's and have 4 more free, and here are my questions:
1. will i be able to install an NVMe later on?
2. why do mobo manufacturers make their motherboards with so many pcie lanes when the CPU's cant cover them all ( not even a 3950x )
3. do the SATA3 storage devices even take up CPU pcie lanes, or are they handled by the mobo?
Sorry for the dum questions.
Edit:
I found this diagram on the net, however i dont understand it
