It's comes as no surprise that the latest dual GPU cards, the Palit 9800GX2, and Sapphire 4870X2 score the highest. At the same time, it's interesting to see how close the single GTX260 and GTX280 cards compare in terms of performance, despite them being priced lower than the performance leader, the Sapphire 4870X2. The most surprising result of this comparison, to me, is how the 9800GX2 is neck-and-neck with the 4870X2, especially when overclocked, even though it costs considerably less. There is a loose rule-of-thumb that the higher priced cards are the best performers. Remember that the cards are ordered in the graphs by ascending price. As the prices increase, the performance doesn't necessarily increase proportionately as sometimes you get less performance! So let's take a look now at the performance when taking the cost of the card into consideration.
