LOL! I'm pretty happy with my voltage-locked 670 card running 1243MHz core & 7GHz memory ... of course it's the nvidia who sets the max safe voltage limit, but wasn't that like this with ANY GPU so far in general?
in past we had cards coming at (lower) set voltage from factory and max (considered safe by OC communities) voltage limit learned by trial and error ... and then checking what clocks can be achieved in that range ...
not much really changed ... in fact it's still exactly same, only difference that it was nvidia who tested what voltage levels can be harmful and locked them out, setting a max limit.
Still each Kepler card can do different clocks (max boost) even though all of them are locked at same max boostable voltage (while idling at lower volts and clocks to save power).
sorry, but to me at least those cards are powerful enough at max boosted clocks and "locked voltage at max 1.17V"
I can also very well understand Nvidia stance against AIBs who are supposed to cover warranty repairs of their own re-designed cards, that were modified to run well above reference speeds and voltages ... why would nvidia pay for someone else's faults?
I like nvidia cards for many things and definitely will be buying another 670 by the end of year to enjoy a powerful SLI at a decent price (which didn't change much if at all versus past releases).
The thing is, we weren't forcibly locked out of higher voltages before. Sure, you run the risk of burning up your card, but at least you HAD that choice to make on your own. Plus. silicon doesn't degrade because of high voltage alone, it degrades because of a combination of high voltage, high temperatures, and low quality components.
Nvidia also makes it seem like over-volting your card will make it degrade within a very short time. That's far from the truth, unless you're running EXTREMELY high voltages (in the range on 200% compared to stock), you won't experience any significant degradation until you're already on your next card.
