I have recently started putting together a core i5 rig: Intel Core i5 2.66 GHz cpu Asus P7P55D Pro LGA Mobo G.Skill 4GB DDR3 1600 memory Corsair 650 Watt psu WD Caviar Black 750GB hdd I'm still up in the air on which gpu I'll be getting, (torn between the HD 4870 1GB, and GTX 275 896GB), but that's another issue. Anyways, I've read on http://www.overclockersclub.com/reviews/intel_corei5750_corei7870/4.htm that the i5 can be safely overclocked to over 4Ghz. I'm not sure I need to go that high and would like to stay around 3.6-3.8Ghz. I also saw this video on overclocking the i5. My question is, does anyone think this video and the overclockersclub site have any validity? I haven't overclocked a PC in about 4 years (which is how old my last desktop, prior to the i5 rig, is).
