how do i know if i bought a crossfire master card or just crossfire ready card?

basically i bought a 1900xtx long time ago and i am thinking about adding in the 2nd vid card. is there a way to tell or find out if i bought the master card or not? cause i can't remember.

another quick question, if i could get the 2nd vid card for around 100-150 would it be money well spent as an upgrade?

hah oh wait, is the master card one with 2 dvi outs and the secondary one has that weird connection for the dongle? if so, i feel stupid and definitely have master card.

according to this website i have an xtx because of the clockspeed.
