Derek from AnandTech has taken a look at ATI's Radeon X1800 CrossFire Edition:
You know what they say, if at first you don't succeed... So we're back here today with the CrossFire solution that should have been: the ATI Radeon X1800 CrossFire Edition. The dongle is still there, as is the master card, but the resolution limit isn't and ATI's finally using a GPU that is a worthy competitor to the 7800 GTX. This time around, ATI has a chance and now, more than ever, do they need it.
