The FX-8350 is the best CPU for you. I agree.
Be aware the motherboard BIOS must be updated, so you need a CPU already to do that if the BIOS isn't currently v1502 or greater.
You didn't say if the board was in an existing functioning computer. If it's a board someone gave you, then you need to find out how new the BIOS is or it might not work with the FX-8350.
