My friend has a 600w (it MIGHT be 630, I can't remember for certain) power supply, and is currently running an athlong XII 640, and is getting some bottlenecking. He is looking to upgrade the CPU without upgrading the power supply. I was looking between the FX-6300 and the FX-8350/8320 I know that his computer can handle the FX 6300 since it's 95w (same has his current CPU), but could it handle the 8350/8320? I've used different power supply calculator,s but I get some different results, so I was hoping you guys could guide me to what would be best
