[SOLVED] Question about Windows

Hi,so my brother just bought i7 3770,to upgrade from a i3 3220.I know a Windows reinstall isnt required,but he says he has a lot of "junk" on it and he just wants a new start.So does he reinstall windows with i3 3220 right before he puts the i7 in or he just swaps the cpu for i7,boots with i7 and reinstalls windows?
Sorry if i put this in the wrong thread.

It doesn't much matter.
Just make sure the BIOS is correct for the i7 IF it needs to be upgraded from the BIOS for the i3.
I don't know if it does. I'm just mentioning it.
