the FX chips are code named bulldozer, they have a dif layout and win 7 dosn't use all the cores to best advantage

I was looking at getting one last month and after reading all the info have decided to go intel (be the first intel chip I bought for 10 yrs lol) win 8 is suposed to deal with it better but I dont want to change op sys at the mo

not looking to put you off, just want you to have all the facts you can get before deciding an if you look Moogal has a phenom! diff chip alltogether(heck 2 of mine are phenom 4 cores)

heres another link with more info (http://www.extremetech.com/computing/99545-amd-fx-bulldozer-desktop-cpu-released-slower-than-cheaper-core-i5-competition)

 

hope whatever decision you make works well for you
