HardOCP has finished their evaluation on ATI's Radeon X1800XT CrossFire:

As we sit here writing this introduction, it dawns on us that it has been three full months since we wrote our last CrossFire evaluation. During that passage of time, we really haven’t been hearing much about CrossFire. This is mostly due to the poor availability of X800/X850 series Master Cards. Furthermore, most people are really not choosing to put their money down on older technology but instead want to wait to pair up ATI’s newest technology in the X1000 series. Well that wait is finally over and X1800 XT Master Cards have finally been released..
