They should have a working prototype at the show but we know that a double RV530-based card is not going to be cheap to produce. We also know that if you want the dual-chip ATI-based card you need to have a special and rather expensive bridge chip to make it possible.
Upcoming RV560 cards will have this bridge integrated in the die and will make the card production much cheaper.
We wondered about the card's performance and, if you think about it, there should not be many problems to make those two cards work in a Crossfire motherboard. ATI does need a special driver to make it possible. We will meditate on this. µ
