Re: My GTX 480 died -- A reliability study.
It seems that this last card was my mistake.
I used NVAPI to stop the card from doing Clock Throttling, and for some reason, after some time it started to show important stability problems. After I reverted to using the control panel instead, things fell back into place. So we can ignore that last dead card. I'll edit my previous post for tracking purposes.
The high confidence most of you have in your card is good sign; Hopefully my dead card was just bad luck.
Note : The dead card was with a Thermaltake 1200W PSU, which always went strong.
