This is from Ryan Smith (GPU Editor @ Anandtech)..
NVIDIA doesn’t believe voltages over 1.1625v on Titan will meet their longevity standards, so using them is still very much going to reduce the lifespan of a Titan card.
There are people who say overvoltage is fine, GPU degradation doesn't really affect until at least 3~5 generation changes (read 3~5 years of use) etc.... But.. IMHO, they don't know what they're talking about. They're in no way designer nor engineers of GPU let alone in semiconductor industry. Think about no. transistor counts packed into a single die. This is no crappy x86 CPU from Intel/AMD nor anything you've seen before. This is one of the most complex, sophisticated silicon you ever witnessed. (Intel's current flagship consumer CPU 3960X/3970X look like a ten year old technology compared to what is achieved in GK110).
For 24/7, I'd advice to stick with 1.150 ~1.162V. This is what Nvidia considers as stock core voltage for GK110.
Personally, I always overvolt my GPUs because I've never used any GPU more than 1 year. I upgrade often. So, I don't really care about the degradation. (I just feel sorry for those guys who buy my stuff. It's one of my reasons I never buy second-hand components. )
