Graphics card buyers reference - ATI Radeon

Although it is generally true that you can expect more performance when you spend more, it is all too easy to buy a card that doesn't perform as well as a much less expensive counterpart.

This guide is deliberately lacking in editorial.  It is meant as a resource so you can choose where your performance/price threshold is.  Although there are many factors to consider, I personally look at fill rate as the real measure of output for a graphics card.  Some of the other stats just describe what the card is working with which will indicate how well it will perform under a heavy load.
