The graphics card marketplace can be quite confusing to the new PC gamer. There are no standardised labels, cards with the same number designation vary from manufacturer to manufacturer, and the internet is filled with people that swear their favourite piece of poly-processing hardware is the best. I've been buying cards for more than a decade, and I still get confused. That's why GPUBoss.com exists.
Featuring the same streamlined interface of its predecessor, CPUBoss.com, GPUBoss.com takes the most popular video cards of the past several years and sorts them by value, performance, gaming power and price. Select a pair of cards and compare, or just run down the list until you find one that's got the right balance of juice and price.
It's a very intuitive site, and while some of the data still needs to be filled in, it does a fine job of presenting the info it does have in an easy-to-understand format. It's like an infographic. Everybody likes infographics.
