also, the sapphire one doesn't have VIVO, though most people don't / understand how to use it so it's kinda moot.
vivo or avivo is just a name for a picture enhancing technology ATi uses. It really only makes a diffeerence with 10 bit lcd's, so in other words it will only make a difference for 1/10,000 users... oh and people with HDCP components.
