Hey guys, I am about to change my CPU to a new CPU, R5 - 1600 to R7 - 2700X
Won't change my motherboard tho.

I believe we have some PC experts here, so I would like to ask, if I change the CPU, do I need to format my PC?
I believe I may need to update my BIOS for that obviously, but will my HWID change aswell?
