I don't criticize people for enjoying a McDs cheeseburger once in a while, nor do I criticize people who spend 5000 USD on a single dinner for two (including wine/tip etc.). Why should hardware be any different? The 'worth' isn't always reduced to performance metrics. As displayed in this thread, some people care about aesthetics, design, power efficiency, noise and heat production, colour, whatever. If you're not in the market for these cards that's fine and dandy, but I'm not sure why some people think that because they don't think a setup is worth it that therefore the people who do spend on those setups are simply being irrational/stupid whatever.
