Yes, that is it. After you uninstall it, it will likely ask you to reboot. Even if it does not, reboot anyways. And if you know how, go into the BIOS and disable onboard video. Shut down the PC, and unplug the power, if you have not already installed the X1800. After shutting down and removing the power cord, put in the video card. Make sure it is seated well, kinda rock it back and forth to insert it. Plug in the power connector to it, and boot the PC up. Once it comes up, it should say it found new hardware, and your display settings with be all whack. Big icons, etc. It should ask you if you want it to install the video card for you, just cancel out of that. It will probably ask you twice. Double-click the new drivers you've downloade (make sure you download them before you uninsall the previous drivers, makes it easier), and install the new drivers. You will have to reboot after doing so. Also, make sure you have .net installed (link on ATi's driver page) if you are going to use CCC, or the bundled version of the drivers.
