Hello tom's hardware dwellers, im upgrading some parts in my system to match my new gpu, im upgrading from a x4 760k and a MSI A78-E35 to a i5-4430 and a ASRock h97m Pro4 board. I have windows 8.1 oem and i a tad bit curious of whats going to happen after i switch the components. Some help as to if im going to need to use cc cleaner to clean old drivers ect. Or if im just going to switch the parts out and boot up and be fine then remove drivers. Thanks for the help!
By the way, the mobo and cpu are already ordered and are scheduled to show up tomorrow.

If i completely wipe my drives and uninstall windows completely would my old windows key work for a fresh install?
