The Phoronix gang's got a photo preview of the ASUS flavor of the X1300Pro posted. Numbers to come soon, no doubt. Looks like ASUS is using a shorter version of the cooler they put on their X800XL.

"Even with ATI's X1900 series launch this week, there continues to remain no official support for the X1000 series under Linux. Although the support should be appended in the near future, today we have a preview of the ASUS EAX1300PRO as well as some exclusive Linux information pertaining to the most recent Radeon offerings."
