Sunbeamtech’s Core Contact Freezer provides adequate cooling and factory-style clip mounting to ease motherboard swaps.

Seasonic’s X760 provides the consistent efficiency required to assess motherboard power differences.

G.Skill’s RipJaws X DDR3-2200 16 GB kit provides the super-high XMP value we needed to evaluate each motherboard’s overclocking capabilities. We used two of the four modules for benchmarks.

AMD’s 2 GB Radeon HD 6950 reference card removes any questions of brand mismatch between the tested CPU and GPU.

    How is this relevant to enthusiast? Bulldozer is out classed by Sandy Bridge I don't care if there are a few less sata ports. If you need to upgrade your better off going with Sandy bridge and z68 or p67 or wait for SB-E and X79.

    thanks for this article. I was waiting for it since some guy said that the 8150 was performing badly because of the mainboard used, but now I see that that was not correct.

    nice thorough review.
    but great chipsets cant offset poor CPU's.

    Yeah If were to buy this boards would be with a Phenom real 6 core CPU 1100T :D that is the smartest choice. I think.

    I would wait till next year to decide. I still feel that windows 7 aint optimized for BD.

    First off, thanks for the great article, good to see Tom's is keeping up the top notch quality!

    Secondly, I would really like to see a piece on extreme CFX/SLI configurations on rigs like this. It seems an article with reliable information on this would be beneficial to gaming enthusiasts, IT professionals, and HPC builders alike!

    Hope to see an article along these lines soon!

    I bought the Sabertooth during the summer and I can attest to how amazing that board is. It's really nice, lots of features and high quality. I'm running a Phenom II X4 970BE @ 4.3Ghz on water right now. Absolutely wonderful system.

    What a bunch of pretzel logic we have in this article.
    Of course, a fan of Intel's work could argue against the need for 42 lanes of second-gen PCIe when the 36 native to X58 Express support multi-card graphics configurations just as capably. But such a comparison really isn't necessary. After all, we've known for almost a year that Intel’s lower-cost Sandy Bridge-based part outperform the pricey six-core Gulftown-based processors in many desktop benchmarks, including pretty much every gaming scenario we throw at the two platforms.

    So, x58 is irrelevant, because SB beats it. Except AMD's offering is somehow relevant even though both x58 and SB beat it. What?????

    If you ignore x58 because SB offers better performance, you ignore anything AMD has because a SB setup offers better performance. If you want 36 or less lanes, x58 still offers better processors than you can hope to get from AMD. Bizarre logic.

    Not that AMD is irrelevant, just the logic is badly flawed.
