GTX 590 reviews

[Sherman Tank]

Instead of being just app detection, it is now hardware based as well in order to limit current before the card exceeds a certain threshold.

I could be wrong, but doesn't this just show that their hardware based solution is ineffective/redundant, considering further power reductions were needed with multiple driver revisions and a rumored bios update?

Overclocking is a value-added feature but is never guaranteed. I know people love to do it but supporting it past a certain extent isn't in NVIDIA's best interest.

It's in Nvidia's best interest if it's cards are robust enough to enable as much OC headroom as is safe for the GPU die, as it allows them to charge either higher prices than they otherwise could, or gain market share.

Then again, you forget that the card CAN be overclocked but is highly limited by its default voltage; a voltage which was put in place to limit power consumption.

While the OCP and locked down low voltage, is to limit power consumption, the reason they are limiting power consumption so vigorously is simply to prevent untimely ends to 590's which they wouldn't have to do if the cards had been sufficiently kitted out.
