Will this work? AMD Athalon 64 x2

A friend of mine is parting out his older system. The computer I have now is just there to hold me over until I build a new system in three to six months. It's currently running a single core Sempron. He's willing to let me have it for $20 with the heatsink and what not. Was wondering if it will work in my board.

CPU: AMD Athalon 64 x2
4200 2.2 GHz

Motherboard it will be going in: Asus A8M2N-LA (OEM) Specs found here:

I found this which makes me think it'll work.

So, should I be good to go? I know it's not a major upgrade, but it's dirt cheap and will last me until I build a better system. Thanks for any responses, and sorry if this has been brought up before.
