Flagship Mainboards for Bulldozer from Asus, Gigabyte and MSI
The excess power consumption on the Asus is troubling however. Asus has had VRM issues in the past so they may need to re-engineer their VRM circuits to prevent these issues.
The Elapsed time (first line) depending on amount of cores shows how fast task is executed when processors are deployed one by one to work in parallel from 1 to 8. Other lines of results are almost irrelevant (they are elapsed time times number of processor and so on). All previous AMD CPUs were beating Intel here almost by the factor of 1.5-2

"One aspect of the GIGABYTE 990FXA-UD7 truly set it apart from the ASUS Crosshair V Formula. That was our experience when we overclocked the AMD FX-8150. When we pushed the FX-8150 on the ASUS Crosshair V Formula, we weren't able to break 4.6GHz with all eight cores active. At 4.6GHz the system would boot up completely normal and seemed to be rock solid. When we tried for 4.7GHz the system wouldn't even post, didn't seem to matter if we pushed more voltage or any of the other tricks up our sleeves. It seemed that our FX-8150 was just limited to 4.6GHz with all eight cores. We were able to disable four of the cores and get to 4.9GHz. The GIGABYTE 990FXA-UD7 turned out to be a completely different story. We were able to bring the system to 4.6GHz, and didn't plan on much more thinking that our chip wouldn't do any more. Turns out it wasn't the chip that was the issue. We were able to increase the multiplier to 24.5 and boot into Windows! We weren't what we call completely stable, but if we were to switch over to water cooling we could pump more voltage and gain the system stability we desire."
