Will an older PCI express 2 motherboard be compatible with a newer PCI express 3 gpu?

Currently I am using a rampage 2 extreme motherboard that says it has support for gddr3 and 2 pcie 2.0 ports. My current gpu is a amd radeon 4870 x2, an older gpu from around the same time as the motherboard (2008). My gpu has trouble running a lot of games and I would like to upgrade to something in the $100-$130 range most of the cards I've seen say they have PCIe 3.0 and GDDR5 memory. Will the gpu be compatible with my motherboard.
