The Inq's got the details on the ASUS flavor of the RD580 chipset. They're saying it'll be a helluvan overclocker, too...

"ASUS will be among the first to embrace the ATI's new chipset. We saw a sample of ATI's reference motherboard at CES, and ATI will announce this board in a few days time. The code name is RD580 while it will be commercially known as the Radeon Xpress 3200."
