Read booklet of your main board . It is very likely that there is
information about effect of using other graphics card in your mother board
. For example , in my ASUS mother board ( Intel type ) , it is said that ,
approximately , "When a graphics card is used , mother board graphics ports
are DISABLED ."

If you can not information about this issue , you may ask to ASUS ( see
global ASUS web site ) .
