Such a roundup seems pointless to me until Bulldozer launches.
Bulldozer bench marks can go into the cpu section. I would like to see USB 3.0, sata-3 and other peripheral differences between the mobo's as well as fan speed control options, power consumption, bios options and stability tests.
All can be done with any phenom II, I mean most sites already tested out the 990FX mobo's.
At least then it would give users a good idea what mobo to get (ahead of time) if they want to go that way.
