Benchmark Results: Synthetic
Futuremark's metric leans toward Gigabyte, with wins in both 3DMark and PCMark Vantage.
Most of the real-world benchmarks showed little difference between boards, making the somewhat-noticeable leadership in Sandra Arithmetic noteworthy for DFI and Asus.
All four motherboard reported dual-channel mode enabled, at DDR3-1333 CAS 8-8-8-24 1T timings, yet Sandra showed a significant difference in memory bandwidth. This appears to be a software issue, since Asus’ score increased noticeably each time we retested it while others didn’t exhibit similar behavior.

I never knew any AMD processors had that much cache!
1.66% better than the worst performer in the tests. :-)
Not much point in throwing that much GPU horsepower at a motherboard review; the card Thomas used is our current reference--and it's more than ample for showcasing the differences between these boards.
If you want to see quad-CrossFire for any specific reason, feel free to let us know and we can put together a story idea!
Consistent would have been better if not for the fear of people pointing out ever tiny inconsistency. Just remember, if you're 5'11" tall it's clear to just about everyone that you're not 6'!!!
Could you clarify that a bit Chris? Are you saying you would not expect any difference in crossfire between the MBs? If so, that's OK. However, if there's going to be a difference, that is the main reason to buy a 790FX. If you aren't going to crossfire might as well get a GX.
I suspect the chipset isn't the whole story and the various manufacturers could still screw up the PCI-E voltages or something :p
