VR Zone has some info on the Bad Axe 2 motherboard from Intel:
As for thermal envelope, Conroe is 65W and Kentsfield is 95W. There is something down the pipeline on Intel Desktop Board roadmap that revealed D975XBX2 codenamed Bad Axe 2, the successor to the current D975XBX.
We got to know that this board is specially made for Kentsfield where optimizations are done especially on the system bus to enhance performance.
Seems like it will be the top choice board for Kentsfield before Bearlake chipsets with ICH9 come along in Q2 2007. We can expect this board to be available in Q4 this year.
