Gigabyte's Full AM3+ Line Up Now Online

[XRL8]

Even X58 "required" two nf200's for Nvidia to allow 4-way. X58 can do 4-way @ x8 link. I'm guessing they've came to their senses and are going to allow 4-way with x8 links?

All amds high end chipsets from AM2 and up had enough pcie lanes to do 4 way sli/crossfire without the need for third party chips.(38 pcie 2.0 lanes)
So theres no change of heart here
As for the x58, there were four variants of the chipset, and two of those offered enough pcie lanes (36 pcie 2.0 lanes) to do 4 way on its own, nf200 chips were used to aquire nvidias license i believe.
The only thing that changed is that nvidia licensed SLI for 990FX.But it works on 790FX and 890FX also, you just need to hack the driver.Its paper/lawyer thing, not technical problem.

I should have been a little more clear. I was talking about the licensing issues and the use of nf200. I know X58 and FX AMD boards had enough lanes, but nvidia blocked it unless you used their junk nf200's.

All X58's had enough lanes to do 4-way with x8 links but nobody made boards with proper spacing for it until the Classified 4-way (with nf200's) and later boards. The first batch of boards would all do 16/8/8 but only because they had triple slots. My question to dino was really about nvidia loosening their grip about using their stupid bridge chips rather than having enough lanes. I think we all know 4-way running at x8 works just fine. ATI thinks so too.
