I'm not sure that's an accurate statement... anything that's used hard will incur extra wear and tear. If you're running a GPU at 100% 24/7 for a year, the heat stress alone will reduce its lifespan. The reason the Xbox 360 had the RRoD problems isn't because it was bad from the factory, it's because it didn't dissipate enough heat so over time the components wore out quicker than expected. I might buy the idea that miners don't stress their cards like the other person said, but I'm not convinced by your statement that running an electronic component hard for long periods of time won't increase the risk of failure. Especially in something as high tech and compact as a GPU.
