Im highly interested in an overlocking custom pc also along with an extreme custom pc which both have exactly same specification except for the CPU or Intel Core. They are both i7 950 but 1 is an Overclocking (3.06Ghz-3.8Ghz) CPU while the other just says "Intel i7 950(3.06GHz)" only which i believe is just a solid CPU. I'm just wondering what the drawback was or difference since the price to both PCs were very much the same. I just want one where it can last long as ive heard the OC uses more power an heats up more quickly but yet is faster. so i wanted to know the difference before i can make my purchase.
