    This was ALL OF THE AVAILABLE 790i Ultra SLI MOTHERBOARDS: Other graphics brands with NVIDIA reference boards INCLUDING EVGA are selling the same unit as XFX, even with the same BIOS (except for the boot logo). XFX was the only one who cared to send one.

    Who would pay four hundred dollars,when you can just buy a P45 for 100-150 dollars which has roughly the same real world experience as an X48 or 790I?
    Nah,I'd rather buy better and more reliable parts-such as power supply,processor,GRAPHICS CARD,and maybe go buy a rifle :P

    $400 for a motherboard? What the hell is wrong with the X48 Express that people would rather consider buying a 790i? And it can't be because of SLI. Makes more sense to buy the X48 and Crossfire.

    If you want SLI you're going to need an SLI motherboard. The article specifically stated that the reference design motherboard was almost as good in many ways as the winning board, but far cheaper.

    The site only has two awards, one is for top value and the other is for "best of the best". It's hard to award a $350 motherboard for top value, but it's not so difficult awarding the "best of the best" even if the price is outrageous

    It does! Well, sorta. If you want the absolute fastest rig on the planet, you're going to need at least two, possibly three, GTX280's. But if you can wait a few days or maybe a couple weeks, you might be surprised at how well a Crossfire set of HD4870X2's can perform using an X48 motherboard.

    My point is that,even though you could theoritically have 3/4 GPU's all at once,you won't get nearly as much performance as you'd want.A simple 750I or P45 chipset will do nearly the same job.

    It is a foxconn board i bet.I just read a review elsewhere with same stuff except it had an x48 chipset."All manner of goodies are bundled with the Black Ops: a 120MM fan, a plastic dry ice cooling pot for the Northbridge, and a Plexiglas "benching table" for open-air use."
