I use a brand-new 520HX with a Q6600 G0@3.3Ghz, 1.3 Vcore + G92 8800GTS@stock. Some of my friends said I will need to replace my PSU if I want to overclock to 3.6-3.8 Ghz. Do you think I will need to replace the 520HX for reaching 3.8 Ghz with watercooling? I do not plan any SLI configuration or GFX card overclocking. I just use 1 optical drive with 2 HDDs. What is the maximum Q6600 Mhz or vcore I can use long term with a 520HX?
