FX vs 4300 vs FX 6300 vs Phenom ii x4 965?

I'm down to one of these three, I mostly play StarCraft2, Diablo3, WoW, Minecraft, LoL. I'm trying to upgrade but which one would be best at stock speeds. I don't know how to overclock and last time I tried my computer turned off and refused to turn back on. So at stock speeds which CPU would be best to run these games? Please I would really like an informative answer I have been researching and have found nothing but conflicting answers.

-Thanks in advance
