   This card is to be an upgrade for systems with planar VGA. It provides support for 800x600 and 1024x768 modes, something the planar VGA could never do. Color depth is limited to 256 colors. The neat-o thing about the 6600 is that it supports 60 AND 70 Hz operation, again, something the planar VGA can't do.

  You can also choose to have only the planar VGA passed through the 6600 or have the 6600 SVGA enabled.
