Intel Motherboard in existence that supports full speed dual PCIe x16?

And that is excluding any forthcoming chipsets. I saw a few AMD mobos with the ATI Xpress 3200 chip, kinda old, idk. Anyway, any thoughts? thanks for the input!
 
ATI Xpress 3200 is x8/x8, it's not dual x16.

As for your original question, it depends what you mean by "full speed". Anything that uses the Nvidia 680i chipset has x16/x16 SLI (but does not support Crossfire). However, not all of those lanes come off the north bridge, some come off the south bridge instead, and there is (arguably) a bottleneck between the two. A better design would have all of the PCIe lanes coming off the north bridge.

We'll see this in the just-about-to-launch Intel X38 chipset. It, however, will not support SLI - only Crossfire.
