i read about peoples problems about how it shows one card as the primary adapter and the second as a disabled adapter even though it is enabled in device manager and such, same thing happens on mine.

Altho this might answer your question from the above site

Q: How come CrossfireX is not working! I'm using Windows XP?

A: CrossfireX (Using more than 2 GPU's) is only available to Windows Vista with Catalyst 8.3 and above.

So, that sounds like a definite answer to me

.

You need 2 things; a Crossfire motherboard. The Crossfire motherboard will come with a Crossfire bridge i and you use this to connect the cards via a port on the top of the card.
