soon I will be replacing my ati 3870 with a sapphire toxic 5850 and I see amd drivers can now be replaced thru steam. now can I exchange cards and install the latest amd driver thru steam or should I delete the current driver,shut down and exchange cards,boot up and install a new driver? thanks
You could use steam... but since you're swapping cards it'd be wise to uninstall, use driversweeper and then install the new drivers, IMO.
If you are using the latest ATi driver, I'm fairly sure its the same driver for the two cards. No Uninstall/Reinstall needed.
