RD790 to gain triple and quad CrossFire capabilities
AMD is preparing to update its
aging 580X chipset
later this year with the
. The upcoming RD790 serves double duty as the
single and dual processor platform
of choice for AMD desktop products. RD790 introduces 41 PCIe 2.0 lanes to AMD’s Socket AM2+ platform for Stars-family processors.
Motherboard manufacturers can distribute the PCIe lanes in many configurations, including four PCIe 2.0 x16 slots with eight-lane signaling. With all 41 PCIe 2.0 lanes, the RD790 chipset has a TDP up to 10-watts. AMD roadmaps reveal the multiple PCIe 2.0 slots are used for an improved CrossFire multi-GPU technology. 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.
Expect RD790 to arrive later this year in time for the
AMD Phenom product launch
in single and dual processor configurations.

Very funny one 2900 card can't beat 8800GTX so what do we do add more cards hell why stop at 3 go for eight or even more.Its the George Bush theory can't win a war just say we need more troops.Can't win against one card add more eventually they"ll get it right.Also don't forget the spin and say we need better drivers.You silly fanboyz crack me up.Blindly following a company for what?

I agree with you that blindingly following a company is retarded.
But at the same time I must admit the ATi/AMD fanboys have a point. As drivers progress the Radeon HD 2900XT 512MB has been getting better and better.
It really goes toe to toe with an 8800GTS 640MB (It's intended competitor) now. HardOCP posted a one sided review where the games they tested where:
1- For the most part not popular
2- Games AMD/ATi have problems in.
Read this review instead:
Like Anandtech reviews it's VERY evenhanded testing more then a handful of games and settings. It put's HardOCP, Fudzilla and Falcon Northwest to shame (all three lying scumbags some making you think the R600 is godly others making you think it completely stinks).
PS - I run an 8800GTS in my P35 rig and two BFG 8800GTX OC Watercooled editions in my 680i.
