Upgrading from 3850 to 5770 - Do I reinstall catalyst??

[tbz_ck]

Quick question:

I currently have a HD3850 in my machine and a 5770 in its shiny new box. Do I

1) simply turn off the PC, swap the cards and off I go,
or do I

2) Uninstall catalyst drivers, turn off, swap card and then reinstall catalyst drivers

Thanks for advice

I went from crossfire 3870's to crossfire 5770's, all I did was power off, new cards in, install latest cats.

Job done.
