On a kind of off topic note...
Its really annoying me that ATi and nVidia both put in artificial driver restrictions to lock Xfire/SLi into their respective motherboards.
Its anti-competitive imho, ATi and nVidia should be required by law to allow their multi-GPU systems to run on Intel, ATi, or nVidia chipset mobos. After all it is supposed to be a free market, and if, for example, R600 turns out to be 3x as fast as G80 and RD600 turns out to have a 270MHz max FSB and dire memory performance compared to nForce 680i, I should be able to choose each on its own merits and go R600+nForce680i
(I know by the way that R600 WONT be 3* the speed of G80 and that RD600 will hit way more than 270MHz before you all start correcting me)
If I want to run R600 Xfire on an nForce 680i, I should be able to. If I want to run G80 SLi on an RD600, I should be able to.
Basically this mobo looks sexy but if I buy a G80 then this cuts off my SLi upgrade path 🙁
