Yes, I just thought about that today, and it turns out that I don't. What would be the best course of action to take? I can't believe I've never checked that!
You can also do it this way. Wait for your new videocard to arrive; install it. Let the computer boot up in Normal mode. Clean the drivers on the normal way. Download new drivers, and DriverSweeper. Shut down computer, boot up in Safe mode. Use driversweeper to sweep the remainings of the drivers. Reboot in normal mode and install new drivers.
