PCIe 3.0 CPUs?

[jelsea]

I tried searching for a answer on this question myself but wasn't able to get anywhere. I have a new PCIe 3.0 ready MB, to use the new 3.0 graphic cards I am told I will need a cpu that has PCIe 3.0, when I take a look at Intel's procs I don't see any that say 3.0 in the specs, they all say 2.0, the one I am looking buy is the I7 3930K, so wondering how that will work with the new 3.0 graphic cards. Thx, for any info you guys can give me.

I don't believe I completely understand what your asking. The type of socket is more important than PCI slot for a CPU so I don't know how a PCI 3.0 slot should affect a CPU. Which PCI 3.0 graphics cards are you referring to?

any ivy bridge CPU has the PCI 3.0 controller. what you are looking at is sandy bridge-E and the pci 3.0 controller is on the motherboard.

Sorry, here is the spec sheet for the proc I want. Its a 2011 proc, and if you look at the expansion section it says, PCI Express Revision 2.0, so not sure what that actually is. Is that the older PCIe version, or is it actually the newer one. So if I am looking for a PCIe version proc do I need to look for the 3.0 for PCI Express Revision?

With AMD, there are no PCIe 3.0 capable CPUs or boards yet.

With Intel any Gen 3 motherboard from the 6 series chipset or any 7 series chipset (i.e. Z77, H77, X79) support PCIe 3.0. In order to use that PCIe 3.0 as well you need either a Ivy Bridge CPU (LGA1155, Core i3/5/7 3XX0 series) or a Sandy Bridge-E CPU (LGA2011, Core i7 3820/3960 etc).

While the specs wont state it from Intels site, those I listed do support PCIe 3.0. Sandy Bridge (LGA1155, Core i3/5/7 2XX0) only support up to PCIe 2.0 on 6 and 7 series LGA 1155 motherboards.

As for the CPU you are looking at, it will support a PCIe 3.0 card and run at PCIe 3.0. I have a HD7970 which is PCIe 3.0 and its working in a PCIe 2.1 slot with no issues.
