2 cards??

[captain204mike]

i have 2 xtx1950xtx cards,,
and i have a dfi mobo with crossfire chipset
do i need the crossfire edition card to use both cards
after i installed the second card in the slot,,, and went to catalyst control, it doesnt show crossfire mode?
is there something in the bios i need to change

one card needs to be the crossfire edition and you get a handy dongle to connect them together.
