Looking to upgrade my mobo.

Hey there everyone. I am looking to upgrade my lackluster mobo. Awhile ago, before I knew anything about computers I bought Dell Inspiron 530s. At the time I knew nothing of overclocking. Fast forward to now and I am kicking myself for not knowing then how to build my own comp. I really want to try some overclocking and just want a better mobo then the pos dell mobo I have at the moment. For my CPU I am running a E6500 wolfdale. I hear its a great overclocker but I cannot OC from the bios with my current mobo. Any suggestions for a socket 775 mobo in the neighborhood of $100? I know for that price I won't get ddr3 or dx 11 support most likely, but that is fine since my gtx 260 only supports up to dx 10 anyways. Thanks in advance for your help.
