A new ATI advisory is out, and it looks like ATI fans are in for an interesting surprise; X1300 and X1600 won't need a master card. We confirmed this with a few AIBs over the last few hours, but it appears that ATI will release a new driver soon that enables Crossfire over the PCIe bus on Radeon X1300 and X1600 video cards - eliminating the need for dedicated master cards.
