Sandy Bridge on Z77 (PCIe 3.0) Motherboard

I am looking to purchase a Z77 motherboard with a PCIe 3.0 slot. However, the CPU I plan on initially using is a Sandy Bridge processor. I know that Sandy Bridge doesn't support PCIe 3.0, so my question is, what will happen with the PCIe 3.0 slot on my motherboard if I use a Sandy Bridge CPU? Will the slot run at 2.0 speed, will the slot not work, or will the computer not even POST?
