Stress testing through Maximum heat output using driver/bios based clock frequencies. No you're not going to push your card to the absolute limit normally but the entire point is stress testing.
Saying that furmark killed their cards implies you have some proof that furmark caused it and that it didn't simply bring out an underlying defect such as a system not designed around TDP (common) or a faulty card.
Furmark does not modify any GPU settings including Voltage, Frequencies, or fan curves. It simply puts the card under a full load.
Suggesting that software that behaves this way is at fault is like taking a broken car to a mechanic and then blaming the mechanic for the problem. The software didn't cause the issue it simply made it apparent.
I'm not trying to be a jerk i'm just saying that if you're going to place blame on something have proof or an actual reason for the suggested problem. People have claimed benchmarks and even games kill gpu's for ages.
Feel free not to risk your own (to each their own) but don't propagate rumor based speculation please and thanks.
