Eruntalion, I'm just going to post what my thoughts are and I'll also tell you where I'm coming from. For starters, I have 4 rigs that I use daily 2 of which you can see below in my signature. I also have a I7 6700k with my GTX 980 on it as well as a 2500k my son uses to game on. I do play BF4 on my Fx rig as well as the others and recently switched my Fx 6300 Cpu into the Fx rig in my signature. I can say the Fx 63xx chip performs just fine for gaming and I do not notice any difference when playing BF4 on it as opposed to my 4770k or my 6700k. That said, the board you purchased may run a Fx 8350 at stock settings just fine, but I do agree with the gents above that you may be better off getting a Fx 63xx processor. They are less demanding then the Fx 8xxx and the ridiculous Fx 9590. Therefore you will likely be able to run the 63xx cpu at a pretty good Oc on the cooling you have and also not put as much stress on the board.
Reason I say all this is because you already have the AMD motherboard and it would be silly to sell it for a loss just to get an Intel rig.
