I am planning on upgrading my CPU to a AMD - Ryzen 5 1500X 3.5GHz Quad-Core Processor. I heard its typically better to replace the motherboard when you plan to upgrade your CPU. I also heard from a friend that Windows 10 can be tied to the Motherboard. So would i need to download Windows 10 to my computer if i plan to use my old HDD still? Or do i need to install windows 10 again when replacing the motherboard/CPU?
