Two things to say, one is you WILL need a new PSU. After running an extremely similar setup to yours for a couple of weeks, the PSU gave out and screwed the computer. Had to take it to a tech at a shop to have it fixed and I don't do that unless it's last resort. Also, you can over clock your cpu way more than that. The FX series are very over clock able. I have my 6300 at 4.6 GHz right now, even had it at 4.1 with the stock cooler seeing as amd upped their game with the stock 6300 cooler in particular over the other FX CPUs. Seeing as I have both a 6300 and a 970, you can trust me when u say you won't be let down. Tomb raider on ultra, crysis 3 on almost total ultra, wolfenstein, same thing. All smooth as can be and seemingly over 60 fps constantly with maybe the exception of crysis at about 50.
