New 3930k! Now what board....?

I can ensure you its PCI 3.0 and its also been proven, if he wants 4 x GPU x79 supports more PCI lanes.

Well, I sure am glad to know that. So why would intel say it's PCIe 2.0?
And why would he get 4 graphics cards? Anything over two GPU is just bad!

Don't get me wrong its one hell of a board and its color scheme i personally like but i do want something with 4 way sli/crossfire compatible, like i said before this is a "because i can" machine, and i do want to do 4x 8970 eventually and water cool it properly but thank you for the advice!

Here he says I know 2+ is not really needed.
There is no noticeable difference between PCI 2.0 and 3.0 as no card is fast enough in existence , my two HD7970's run in PCI 3.0 on my R4F perfectly fine.

Awesome! I have two matrix 7970. Love them.

And. For gaming the difference is small. But for intensive apps it does make a difference. Because in gaming the card is the more intensive, but in GPU acceleration apps the heavy player is the CPU. That is why PCI 3.0 is important.
I did some research, Not all X79 motherboards support PCI 3.0 right out the box.
Some of them can... After a patch
This is very interesting, why would intel say PCI 2.0 when in some motherboards it's 3.0?! I'm confused.

Imho those boards are prepared for the next generation socket 2011 cpu´s. the same as happened to the latest Z68 boards that admits the ivy bridge with pci 3.0.

Thanks for all the advice and research guys! after some research of my own i believe that JMMP here is absolutely correct. The old sandy bridge - e chips were equip with the on board PCIe 2.0 controller because that's what the majority of boards and cards could even utilize, but now that a lot of boards have PCIe 3.0 and graphics cards continue to get faster and faster Intel is preparing for the release of the ivy bridge -e chips and now there is PCIe 3.0 on most if not all of the x79 boards. And lets face it these chips are perfectly capable of handling PCIe 3.0 XP

R4E and R4F definitely support 3.0 its only some Nvidia cards that need a patch to enable it. AMD cards automatically enable it.
