Graphics card is definitely worth overclocking (which you have done). It will make the most difference when gaming. The CPU - not so much, but it depends on the game. Some titles are more CPU dependent than others.
My last GPU was a 7950 and I know they are good overclockers, so take it as high as you can.
An i5 4670k is going to be pretty quick at stock speeds so you probably don't need to overclock it, but some extra free performance is always worth going after. Read up about offset overclocking as that's the best way to do it.
Don't worry about PES2014. It's a pile of shit out of the box. Even if you play the game at 60fps, replays look like they are running at 20-30fps. It's just how the game runs. Badly optimised for the PC with stutters and hitching.
NBA 2K - I had issues with this game when I had AMD cards. It was a stuttery mess. Try playing it through Windows Borderless Gaming (http://forums.steampowered.com/forums/showthread.php?t=2675769) - smooth as silk for me. You could try other games like PES through this as well.
