So Im upgrading my little sisters pc. She needs it as its currently thermal throttling due to the poor air flow and low performance. She is currently running a 6800K apu system with 8 gb 1600 mhz ram. Im putting the system in my old fractal r4, giving her my gtx 770 as ive recently upgraded, and powering this with a 500W 80+ bronze psu. I know thats lower than the recommended 600W. The thing is these are all parts I already have. Should there be any concern with these upgrades and the power suppy? I would like to overclock her apu with a 212 evo as her favorite games are cpu intensive. I know apu's benefit from higher frequency ram, should I consider this as well or leave it as I'm going to be putting in a discreet gpu? Let me know what you guys think. I was going to do this all in a few months for her birthday but she mentioned her pc slowing down significantly and upon my inspection I found the major thermal problems the performance is suffering from. So i figured I would do this soon rather than make her go through the inevitable automatic shut downs from the thermal protection.
