The 260x will run most games at 1080p around med settings at 60fps. For optimal game performance, I suggest spending a little more on the graphics card and a little less on the CPU (an FX-8320 or even a 6300 paired with an R9 270x or 280).
14GB of RAM is not good for your system. The amount is overkill, and the only configuration I can think of to arrive at that number would hurt system performance - having an 8GB, a 4GB, and a 2GB stick would put your RAM in single channel mode instead of dual channel, which hurts system performance.
8GB of RAM is enough for any game out, and ideally you buy it as 2 identical 4GB sticks, preferably in the same kit.
What is your budget?
