Copies of Windows aren't tied to any individual install but to the hardware itself (and even then, Microsoft is more tolerant of this than ever before). Just make sure your copy is tied to your Microsoft ID. Would need more details about your PC for anything more specific.
I have an i7 7700k, GTX 1080 ftw, a new MSI SLI plus mobo (recently replaced an Asus mobo due to errors and malfunctions), a Seagate drive (1 Tb).
