[SOLVED] M.2 SSD compatibility in B450-f Gaming MB

[davidmraz44]

Hi,
I am thinking of purchasing an average M.2 SSD (Kingston A40 240 GB). Although, I have read on some sites that in my setup (see below), this would cause the GPU to go down from PCI-E 3.0 x16 to x8.
My question is; is this true? How much would the performance be affected?
Also, assuming I would have the M.2 SSD, would AMD crossfire get potentionally affected by this? As in, would the second GPU (which I am also thinking of adding - it would be little less powerful than the rx570) get reduced from x8 to x4? How much of a performance improvement could I expect had the M.2 not been installed and how much would it change if it had been?
Sorry for the wording, hope the question is understandable.

Setup:
MB: Asus B450-f Gaming
GPU: Asus ROG Strix RX570 Gaming
CPU: Ryzen 2700X
RAM: 16GB
HDDs: Samsung EVO 240 + 2 generic Seagate HDDs

Yes according to the manufactures page ->

ROG STRIX B450-F GAMING | ROG Strix | Gaming Motherboards｜ROG - Republic of Gamers｜ROG Global

Best AMD AM4 B450 Ryzen ATX gaming motherboard with advanced cooling, Aura Sync, SupremeFX, dual M.2, Intel LAN, and USB 3.1 Gen 2

But to be honest it's not worth getting a m.2 only if you transfer files alot. Programs and windows will not launch alot faster than a normal sata ssd. (Yes it will be faster but it's only 0.5 to 1 second.)
