You need the aftermarket cpu cooler too, like the H2O because the fx9370 will run very hot.
And I have a big question for you, what are you going to do with fx9370, for games or for multitasking like photoshop, video editing.
If for game you just waste the money, because most of games don't use more than 4 cores. Get the fx 8320. For other like photo/ video editing etc, you are better to get the i7 that is better than the fx9370. If you want to for ocing , then it maybe the only reason to buy the fx9370.
