AMD and PCIe 3?

Are there any AMD chipsets (which Gigabyte uses) which support PCIe 3.0? I've done preliminary searching, and only found Intel based mobos have PCIe 3.0. (And to answer the inevitable question, no, I will not saturate PCIe 2.1, but this is [H], so PCIe 3.0 it must be!)

Thanks,
Ken

Edited to add the Gigabyte comment. I found Asus mentioning PCI2/3 support, but not Gigabyte. They have the same chipset (990fx). Is Gigabyte's marketing department missing an opportunity, or is there a technical reason for their omission of PCI 3.0? (Or, is Asus stretching the truth?)

asus are probably using a PLX chip to bond together the 32x PCIe 2.0 lanes into 16x PCIe 3.0 lanes, at least insomuch as having equivalent bandwidth.

how efficient it will be, with due consideration to increased latency from the PLX itself, as well as not having access to the the latency reducing tech in 'genuine' PCIe 3.0, is another matter entirely.
 
The current 9-series lacks PCIe3, the upcoming 10-series chipset lacks PCIe3.
 
There's an upcoming 10-series soon? Associated with what new set of FX chips on what socket? I can't imagine with all Intel has done etc... now that AMD won't try to at least compete by providing top-of-the-line chipsets/motherboard features for cheaper. No PCI-E on the 990FX successor is insane, in a day when Ivy and Haswell mainstream lines on Intel have supported it. Thinking about it, maybe this is the way for AMD to get back some enthusiast sales (aside from just plain creating FX chips that compare favorably with 4770K etc in both single and multithread performance etc..); to offer best of breed features for their motherboard chipsets. Sabotaging their possibility for success by forgetting PCI-E 3.0 when AMD makes high powered video cards seems mentally unstable.
