Will a PCI Express 3.0 Graphic Card work with a PCI Express 2.0 board?

[Thebrothersgrim]

I want to know if the "SAPPHIRE 21197-00-40G Radeon HD 7970 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card " is compatible with my GA-970A-UD3 motherboard.

Yes the PCIe std is backwards compatible.
