Question about installing new video card?

Before I install it do I need to uninstall the drivers from my old video card? Or will installing the new drivers just overwrite the old ones?|||Yes it is best to go ahead and download the latest drivers from the ATI or Nvidia website. Then go go control panel/add remove programs and uninstall the drivers. The system will reboot. Shut down, put the new card in and boot up. Now install the drivers for your card you downloaded and it will reboot again. Now you are good to go...
