I would still just use one card. Uninstall the old one completely, drivers and all and install the new one. If you have two cards installed, windows will recognize both and attempt to run drivers for both and this can cause more problems then its worth. Just replacing the card with your newer card, and uninstalling old drivers and installing the new ones should not hurt your video editing or any other programs on your computer.
