HEXUS has posted a review on the ASUS EAX1650XT 256MB (X1650XT Single Card, and CrossFire)

There's no need for a special CrossFire Edition of the X1650XT, as the RV560 GPU has a compositing engine built in. So read on to see how the Asus stacks up to the value competition, and whether ganging two of them together gives a worthwhile boost.
