Very true - one guy I was speaking to yesterday also has a 1.3000 VID Q6600 and he can get 3.85GHz Prime stable at 1.49v... I needed 1.6v to get 3.8GHz futuremark stable, so it probably needs over 1.65v to get it prime stable. In my personal experience, and from what I see in this forum especially, the lower VID chips 99% of the time are the best overclockers/the least voltage hungry.
