680 gtx on a pcie 2 motherboard?

Hello, so I'm planning on upgrading my graphics card. My question is if I buy a 680 gtx(I might buy two to sli), will it work on my current motherboard? My current motherboard is ASUS P6T Deluxe V2 LGA 1366 Intel X58 ATX Intel. or do I have to upgrade that as well(which I don't want to do because that means I have to reboot my whole computer). thanks!

Yes it will work just fine.

hmm, ok thanks. So pcie versions don't matter?

Not much for gaming. The main change between versions is the amount of bandwidth per lane of a PCIe link. From 1 to 2 and 2 to 3, the bandwidth per channel doubled. That means a PCIe 2 x16 link has the same amount of bandwidth as a PCIe 3 x8 lane. Saying it doesn't matter is far too simplistic, but most users aren't going to see a difference.

Hmm, AMD said that the HD 7970's receive a 5-10% performance boost using PCIE 3.0 than 2.0. That's AMD though, I don't think it will make much of a difference
