i seen an article on Anandtech a few days ago but its down again. it was about 15 pgs long and looked real nice. it was a comparison between the old crossfire board and new 580 board by Asus. the Asus board will only be able to run the vcore voltage to 1.65 which for opteron users isn't very good, but the rest of the features are all there now lets just wait and see how good the DFI board is, oooo i feel its gonna be a hot one
The Asus boards will be ready for release March 1st and the other boards will follow around mid march. Like the DFI, ABIT as well as others. The DFI will support full 16 PCIe dual lanes and pretty much looks like the nForce Ultra D Expert board.
