If this is a gaming PC then it's a very odd one. The i7 4770k is a high end consumer processor with a lower end GPU, it doesn't match.
If gaming get a 4670k and spend more on your GPU.
If your PC is another use then it may be okay, as posted what above. What is the purpose of this PC?
Ok nevermind it's a gaming PC, look at getting a 4670K + 270,270X or if you can afford it GTX 760.
It makes more sense.
