I used simple wording in my previous replay to OP.

This time I will be slightly more wordy as I understand the situation facing us with FX processors.
Having followed the early AM3+ chipset hoopla; there's only one true AM3+ chipset, and that's that 9XX series. The 8XX series boards that support AM3+ only do so because they have a modified BIOS, not really because they were meant to support it to begin with. The 9XX boards also use a different system for power regulation, so if you're planning on overclocking, the 8XX boards may not take kindly to it. AMD3+ spec calls for 145Amp power circuit instead of the earlier 110Amp power circuit. The 9XX chipset also features a faster HyperTransport, 3.1 vs 3.0. In addition the 990x and 990FX have support for SLI with Nvidia cards. In addition AM3+ CPUs in AM3 boards is not officially supported by AMD as far as I can determine.
I see many cobbled together groups of components to create mATX AM3+ motherboards and give onboard graphics to the cheaper motherboards including black AM3+ sockets, but have such boards been really RE-engineered for the AM3+ FX processors? Personally I would have my doubts. Collectively, most of us know that it takes a motherboard up and beyond entry level to really handle a heavily overclocked FX series processor and especially so the 8 core FX procesor series and probably the 6 core FX procesors when overclocked.
We have a number now and have had users with these pieced together boards rated to run FX processors that are just not up to the task by the time the user gets into an "overclocking forum" and want more speed since that is the major claim to fame of the AM3+ processors. Generally they must be heavily overclocked to run with the Intel crowd and especially so when gaming is the major concern of the DIY system configurator.
So I guess I could have said no AM3+ motherboard with an actual AM3+ chipset; that would be the 9xx chipset series, supports onboard graphics. There, now I have said it the way I actually believe it. If I were going to utilize an FX-8350 cpu as the OP said he wanted to do and overclock it with efficiency, I see no motherboards that seem to be capable of such operation with onboard video.
