RD790 To Have Quad CrossFire?

According to this article on DailyTech, AMD is preparing a chipset that will be the basis for future high-end motherboard, the RD790.  The RD790 is supposedly going to support not only dual CPU sockets, but also up to 4 graphics cards.  This could be the very platform for the next generation “Quadfather”, or “Quadfather 2.0” if you will.
“The improved CrossFire multi-GPU technology supports up to four ATI Radeon HD 2900 XT graphics cards in Quad CrossFire configurations.

Unlike NVIDIA’s SLI, which supports dual or quad graphics cards in SLI, the improved CrossFire solution can take on three cards for improved performance. AMD claims CrossFire scaling with three cards yields a 2.6x performance increase. Two cards in CrossFire yield a 1.8x performance improvement. AMD roadmaps do not divulge how well CrossFire scales with four GPUs.”

As always, the question is, when? We'll dig and and try to find out soon enough! ;-)
