Hi, just thought I'd throw my 2 cents out there, I'm no pro at this stuff, but I just bought and returned the 9370 and ended up with 8350
and am MUCH happier.
The 9370 ran around 55c when my computer was idle and then jumped up to about 70c when playing battlefield 4, luckily I was paying attention to my cpu temps. I immediately shut down, let it cool down, and took it back and came home with the 8350.
It overclocked to 4.3 and ran under max load at 28c which is half the temp. Not to mention it requires half the power. I have a corsair H80 cooling system and it still ran that hot so just be aware of that as well, you might end up having to fork out more cash as well for a cooling system if you don't already have it.
Anyways, performance wise the 8350 actually felt a lot smoother to me than the 9370, it also bumped my fps in BF4 up to around 70-90 constant on high graphics, where as with the 9370 I had to run on medium and it was still chugging around 40-60fps.
So in my non professional opinion, the lower temps and power consumption of the 8350 trump the 9370(not to mention it feels like it performs better) Okay that's all I got, good luck!
