ATI RD580: Dual x16 Crossfire Preview
Anandtech previews the nextgen ATI RD580 chipset offering a full 32 lanes of PCIe connectivity. Also in the article are some tidbits about the (surprising) performance of the X1800XT Crossfire vs the 7800GTX 256MB SLI.....

The comparison of the RD580 Dual x16 motherboard with X1800XT Crossfire to Asus A8N32-SLI with 7800GTX Crossfire seems a logical comparison to this reviewer. Comparing these results, ATI wins every benchmark. That means if RD580 and Crossfire were shipping today the graphics war would be on and plenty hot. The reality, however, is that X1800XT Crossfire and X1800XT PE are coming soon, and ATI RD580 will likely land in early to mid January. We also expect the ATI R580 GPU to land about the same time, and ATI is hard at work on Socket M2 offerings to be launched with that AMD socket.
