I'm not entirely surprised by these results. I'd point out that there are hardly stock GTX 280s that are being used; they're not only XFX XXX cards, they appear to be core clocked 15 MHz above the actual XXX cards, 685 MHz to 670 MHz. (link, the card model's not available on NewEgg
) At least nVidia could do something right, getting $1,410US worth of video cards, overclocked, to beat $1,100US worth of cards.
However, I'm curious, when I read, "I still feel the Skulltrail board has some minor issues with the ATI cards, something we noticed at launch with the last Radeon series," that if perhaps the benchmark results might be different had this been on a single-CPU board rather than on a Skulltrail. Perhaps some enterprising reviewers might fill us in on that area... I'm a tad disappointed that it appears that none have thus far.
