The processor AMD FX 8350 Octa-Core replaces since Christmas something my old Phenom X2, which Mitlerweile is completely overhauled, with its ~ 2GHz. Performance-wise, I am completely satisfied (with the Asus Radeon R9 280 and Kingston 2x 4GB DDR3 Ram). However, the included fan of CPU's with me permanently at about 6400 RPM, accordingly, the PC sounds like a jet. To buy an extra fan is therefore my recommendation would that day also order a new fan.
However, price performance is great, but a star deduction for the fans.
