Your cpu is good but your gpu is pretty dated. Most games out right now are much more gpu intensive than cpu intensive. This could change in the future as games start to use more cores/threads. With that said, if you can afford it, I'd upgrade the gpu and psu. A GTX 780 and a 600W psu would make your system be able to handle anything out right now and anything released within the next couple years on max settings. To be sure or get an idea, go to systemrequirementslab.com to see what games you can run or not.
