We just built the same build u r looking at for my son. FX6300, R9 270x, 8 gigs of Ram, but used a Corsair 750 (got at a great price) and it is a beast of a setup. Runs BF4 at ultra at 60 FPS on a 30" Samsung TV...ridiculously clean. The build can probably provide faster FPS but the TV is only 60hrz so I thinks that is as fast as the TV will allow (I think thats how it works). This setup alos runs Planetside 2 at 60 FPS on the highest settings. He couldn't be happier. I think with a quality PSU you will be really happy.
