Surely, there is the place some particular "extra sturdy" models for "enthusiasts" aka people with inferiority complex. But for an ordinary use, there's no need in every single card to be OCing monster. And quality PCB and components shouldn't be the part of only tripple. four slot "Gamer" card abomination. That's not mentioning the fact, that quality components, running cooler by themselves, so it eliminates need for huge coolers altogether. And BTW small card =|= doesn't mean bad quality/inferior product. At least shouldn't.

I'm personally tired, of AIB's slapping the coolers from xx70/80, x700/x800 class cards on something like xx60/x600. There's no reason to push these cards with impotent bus that far, except to justify the inflated price.

But the problem behind this is far beyond the sole "reasonability level. It's huge. People do not realize that, but, limagine how much resources being wasted on something, that could be made in compact size and shape. How much copper, aluminium, PCB components and other materials being wasted, that could be used for really more demanding cards, or even other areas. Which inflates the price of said materials by itself, even more.
And for years, medium/low end cards used to be compact by a reason. Because, the GPUs were much more cut down, which already eliminated the need of big cooling, and hence big PCB, etc. It was simply not reasonable for AIBs, and GPU makers to build such expesive stuff, for something, that is just to be honest are cut down leftovers.
