I recently got a new pc, but it was a prebuilt business one, and I'm kind of a mild gamer. The processor within it is absolutely immense, 4hyper threaded cores, 4770k, but it has no graphics, and the game I want to play, planetside 2, is graphics intensive, so I normally only run at 15fps, 9 in big fights. I spoke to my friend, who is good wih computers, and he says, the processor is better than his gaming PC, but I need graphics, so I spoke to a nearby pc store, and they said I should get the 760, but will I need to get a better PSU or anything to go with this?? Thanks for the help
