Im not taking sides on this issue as I have no facts in either direction. But the way I look at it is most hardware is going to drop in value a large amount after 1-2 years and anything after 2 years it is pretty much worthless. I used to be an overclocking nut as well as a Folding@home nut. I have run a fair amount of hardware out of spec and at some pretty high temps with only a few failures. If I can get 2+ years out of it Im happy because after that time no one wants it anyway...
Just my opinion.
