Do I need to reformat after a new CPU installation?

Or is it a plug and play type of thing?

No

If the cpu needs a bios update, do that before you remove the old cpu. Then clear cmos before installing your new cpu, select load optimal settings at post or configure manually.

I second that ^
To know if bios update is needed, refer to the mobo's manufacturer website.
