Need processor help

I'm looking to upgrade my processor without changing the motherboard. I know the processor was not soddered so the instillation shouldn't be too hard but I am not very tech savvy when it comes to figuring out where I might find compatibility issues. Currently im running on a AMD Athlon II X4 635 at 2.9 GHz. I know I need to stay with a four core AMD if I dont want to switch mother boards but is it possible i could go from having an Athlon to a Phenom (looking at the Phenom II X4 980 Black Edition Deneb 3.7GHz)? Any recommendation possibilities would be appreciated! Thanks guys
