I have an Aurora with an i7 980x CPU. A week ago I new nothing about overclocking. I read what I could find here and other places for a few days then I started to carefully experiment with the BIOS (A11) settings. After a few days I've settled on an overclock setting that is a big performance boost and is very stable. I've been carefully watching my temperatures and torture testing with Prime95.
The weak links in my system are slow Corsair ram memory and a SATA II bus.
