Help selecting Mobo!

I'm fixing to buy an AMD FX-4100 Zambezi 3.6ghz - http://www.newegg.com/Product/Product.aspx?Item=N82E168... -

And I just dunno what Mobo to purchase with it... My current mobo will NOT support it. I was looking at an ASUS saber tooth - http://www.newegg.com/Product/Product.aspx?Item=N82E168... -

But 180 is kind of high in my budget. I can do it, but I wouldn't know if it would really be worth it. I really like AMD, and ASUS...
