I've always wondered, what exactly is the market for these cards from AMD and Nvidia? The performance seems about as good (probably lower actually considering how much more powerful CPUs have come since early 2007 reviews) as a 8800GTX/3870 from 4 years ago.
Surely gamers and folding@home/DH enthusiasts enjoy playing with high(or high-ish/medium-high) details and they don't have the horsepower to compete there (not to mention, once you go below medium details, games tend to look much, much worse than even on a console), they're not the lowest power/lowest end card so they tend to mostly have active cooling and power consumption you wouldn't want in an HTPC. Everyone else just using the internet and general working can get by with onboard, or if really needed a lowest tier card, so what is the rationale for purchasing something like this?
