Hello, everyone. Thank you all for your answers it really means a lot to me receiving help. Just a quick update, I've bought the parts:
-Ryzen 5 2600 (couldn't get the 3600 because my budget isn't enough, unfortunately)
-MSI A320M-A Pro M2
-2x4GB Kingston Hyper X 2666Mhz
Talking to the shop employees, one said that upon booting the system with my old drives, my Windows 10 license will be deactivated as a result of me installing a new mobo. I could still use my pc and still have my files, programs, and such I just wouldn't be able to change a few settings according to him. He added that in order to reactivate my Windows 10 license, I should purchase a new one. Would that be correct? Thank you all for your support. Cheers!
