Take the old one out and put the new one in. Install drivers yourself if need be. Also see http://www.wikihow.com/Change-a-Graphics-Card
It's proper to uninstall the old graphics cards drivers first...before shutting down. The same as removing/swapping any piece of hardware on hyour system. Add/Remote programs is the place to start, if it doesn't list your graphics card drivers there, go to Device Manager and remove it. Also before doing all this, I download the latest drivers for my new graphics card..and have the downloaded installation file ready to go for my first bootup. Because on your first bootup, your new graphics card will likely load with some default VGA adapter mode..and your desktop screen will look like it's running in safe mode, low resolution etc..so you don't want to go surfing online to find your drivers like that..have 'em handy and ready ahead of time.
Since a graphics card can easily be the most power hungry device in your system, it is critical to ensure your power supply can handle the added demands of the newer, more powerful card and that your existing power supply has all the necessary power connections for the new card. Many newer cards require additional power connections.
