2 x PCI Express x16 slots, running at x16 (PCIE_1, PCIE_2)
* For optimum performance, if only one PCI Express graphics card is to be installed,
be sure to install it in the PCIE_1 slot; if you are installing two PCI Express graphics
cards, it is recommended that you install them in the PCIE_1 and PCIE_2 slots.​
Š 2 x PCI Express x16 slots, running at x8 (PCIE_3, PCIE_4)
* The PCIE_4 slot shares bandwidth with the PCIE_1 slot. When the PCIE_4 slot is
populated, the PCIE_1 slot will operate at up to x8 mode.
* When an i7-5820K CPU is installed, the PCIE_2 slot operates at up to x8 mode and
the PCIE_3 operates at up to x4 mode.
Looks like the speculation on the 5820K having less PCIe lanes was correct. 40 for the 5960X and 5930K. 28 for the 5820K.

Fixed, I guess that is how they get you to get the higher models if you want to run multiple GPUs.

You can still run 3-way SLI with the 5820K. This really isn't a big deal. It's just going to be 8/8/8 for 3-way SLI or 8/8/8/4 for 4-way Crossfire. That's enough bandwidth considering it's PCIe 3.0. The only real negative here is that forums are going to be flooded by morons who don't understand why their cards aren't running at x16/x16.
