Our best DDR3 memory was shipped in triple-channel kits, so we divided these into dual-channel kits for Socket AM3 compatibility. AMD supplied the processor.

Western Digital’s 10,000 RPM 300 GB VelociRaptor kept load times low and write performance high.

Today’s benchmark suite has several 64-bit updates, but readers should look for additional improvements once all of our editors have reached a consensus towards standardization.

    I never knew any AMD processors had that much cache!

    1.66% better than the worst performer in the tests. :-)

    who said Phenom II has low cache size i think with those 86mb you can do amazing things!!

    sorry about the double post but i would have liked to have seen these benchmarked with two 4870x2's... since they keep talking about them so much.

    Super CPU fixed ;)

    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!

    I think people would like to see a dual-295/dual-4870x2 series of benches if only for the "OMG BEASTLY!" factor. I dunno. XD

    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
