Unfortunately this mobo supports only Phenom II/Athlon II CPUs. U should look for mobos whose chipset is 970(budget)/990X(better)/990FX(enthusiast):http://www.techpowerup.com/reviews/AMD/FX-8350_Piledriver_Review/2.html
And there are some 760G/780G mobos who claim support 95W/125W FX-4xxx/FX-6xxx/FX-8xxx CPUs but these chipset are too old and won't be pair well with FX- CPUs.
Phenom II is aging but still powerful. Good overclocking can maximize its performance (but also need good CPU cooler to cooperate)
