Jon Bach (President) Says:
I don't recommend the 6800K processor. It only has 28 PCI-E lanes, instead of the 40 PCI-E lanes found on the rest of the CPUs in this line. That creates some odd effects on many motherboards, where slot lane allocations are modified, creating more constraints and problems. If you're going to go with the high end X99 chipset, do yourself a favor and don't cripple it by using the bottom-of-the-barrel CPU in that product line.

Jeff Stubbers (Tier 3 Consulting Lead) Says:
If you plan to run multiple graphics cards in SLI or Crossfire, or fill up several PCI-E slots with expansion cards, I recommend against this CPU. This CPU only has 28 PCI-E lanes, which means it won't be able to support full performance to the cards in either of those situations. So instead I recommend choosing any of the other CPU options in this line, as the other CPU options will provide a full 40 PCI-E lanes to properly support the bandwidth of the additional cards.
