Asus p8z77-v Lx switch to Asus p8z77-v Lk

[ThebombT]

Im switching my current mother board which is an asus p8z77-v lx to an asus p8z77-v lk because lx only supports crossfire so i have to switch to lk version thats supports sli for my gtx card. My question is will it affect my ssd which has the os in it.It has all the bios like ai auto suite( which has my cpu oc settings) and the drivers for the lx Mobo. I also have a 1 tb for storage. How will it affect my files if i switch mobos? Shud i do a fresh install?
