Later this year, I plan on upgrading my GPU from a GTX 570 to a GTX 680, but I'm not sure about the power requirements. One of my friends has said that I'll need a more powerful PSU for the 680, but research has shown otherwise. I also intend to overclock both the GPU and CPU (i5-3570K), so I'm sure that has to be taken into consideration. Any help on the matter would be appreciated!
