With the FX6300, you have plenty of motherboard options. You can find many good boards for under 100USD such as:
ASRock-http://www.newegg.com/Product/Product.aspx?Item=N82E16813157394
Asus-http://www.newegg.com/Product/Product.aspx?Item=N82E16813131872
Gigabyte-http://www.newegg.com/Product/Product.aspx?Item=N82E16813128602
These three boards all feature the exact same things, only differences being brands. With the brands being different, each board will have its own unique features that the company has applied to them. The only things these boards lack is SLI support and USB 3.0 headers. This means you will be unable to use multiple nVidia cards in SLI, but you will be able to use Radeon cards in Crossfire. Also, it will be impossible to take advantage of USB 3.0 slots on the front of your case without an adapter of some sort.
If not having the 3.0 headers is a deal breaker, all 3 companies offer an upgraded version of the previously listed boards that support USB 3.0 headers for only 15USD more. These upgraded boards also offer support for nVidia SLI.

Hope this helps and if you have any more questions or want to know any more about the boards, OR are looking to get a higher grade board, feel free to ask!

EDIT: It appears the second Gigabyte and Asus boards I listed do not support SLI. The ASRock does, though. My bad!
