yes, all of the FX processors from AMD are going to experience about a 10% jump in performance when windows 8 comes out, but that's about it.... as the FX processors are generally marketed towards gaming i guess its not really going to help very much in multi threaded applications thus meaning the 8 and 6 core FX processors wont see much of an increase compared with the quad core line of processors (FX 4xxx). I would expect that the FX 4170 will benefit the most from win 8 but i cant bee to sure without looking at some benchmarks.
