I am updating my video card from a 9800 GTX to a GTX 560 Ti. I believe they use the same driver and I already have the latest driver installed. I was wondering if I should uninstall the driver, put the new card in and then install the driver again?
Or because I am using the same driver, I can just swap the cards and it will work?
Typically you don't need to worry about jumping through any hoops. Just replace the card and install the driver when windows boots up under the new card. Rarely will Windows have serious enough issues to prevent you from installing the new drivers.
Come to think of it, I'm pretty sure I've never installed the correct drivers before installing the video card, and I've been doing this since before the days of AGP.
No video is fairly rare. You can also rarely have Windows crash on startup. Usually things will just work, though. With stuff like this I tend to err on the side of laziness, because it saves a lot of time when it works, and it almost always works.
I'd never cut corners if it had any chance of damaging the hardware, but with this your worst case scenario just means you have to go back and do what you tried to skip.
