there's supposed to be a performance hit with this (if you're not using the dongle, that is) so this isn't really worth our time.

so does this allow crossfire without master slave card OR without cross fire mobo OR without dongle.

without dongle is the most useless one.

So far, it's sounding like it just doesn't require the mastercard or the dongle, but a crossfire mobo is still required. Sucks, as I have an X1900XT on a SLI board and I wouldn't mind grabbing a used second card in a few months when people start selling them off when they upgrade to Dx10 cards.

I'd appreciate any info anyone has on this subject. If you can use two non-master cards for Crossfire, then this might be my cheap way into Crossfire since I have a Crossfire enabled 975x board.

I submitted an Info request to AMD/ATI's driver support team asking for clarification. On the Rage3d forums, the 2 or 3 people that have tried to do software crossfire with X1900s and the 6.11 driver haven't been able to get it to work on their crossfire boards without the dongle.

u don't need the master card or dongle to run 2 x1900 cards in crossfire so long as u have a crossfire supporting motherboard.i think one site did a preview with benchies.www.it-review.com(i think,not sure)

Err, no. All this is is that you can mix any two crossfire capable cards of differing models and they'll work in crossfire, although at the least common denominator. It does NOT alleviate the need for a master and slave card, nor does it remove the need for the dongles on anything other than the X1950 Pro and X1650 Pro.
