in any case for both models I wouldnt recommend any 8 core vishera 125W processor; neither model have VRM heatsinks; the LX has only 3+1 phase. the usb3 has 4+1.
They both have piledriver bios support but u need to update the bios. Even if it says no FX 8350 support, so long it supports other models (i.e. FX 8300, 6300) of the same family it should run the FX 8350
My concern for u is that at load, the mb vrm will probably go pop. If your mb is the LX, get a new mb. if it is the 4+1 usb3 model, undervolt the FX 8350 and get a cheap 8 cm fan to blow on the vrms.
