I've got a build very similar to yours. It can play any modern game on at least 30-40 fps (the most intensive one being CoH2), with every setting on Ultra. On Medium-High? You'll be VSYNC'd at 60 fps, no problem.
You'll be fine!
And if your build does get dated after a while, you could buy a better cooler for the CPU (Hyper 212) and GPU (Kraken G10), and with that PSU, you'd be fine to OC to a decent degree.
