PureOverclock has published a review of the Sapphire Radeon HD5830 1GB graphics card.

Between ATI's Radeon HD5850 and HD5770 is a gap in terms of performance and price in their lineup. Looking to close that gap is the Radeon HD5830. Sounds pretty simple, but there is a catch. The catch here is the 5830 isn't a new card, not at least in the traditional sense. Instead, ATI has recycled a piece of their current lineup in order to fill the need, and the 5830 is essentially a neutered 5870 that couldn't pass strict binning criteria. Sapphire has taken the 5830, installed a heatsink with some heatpipes, slapped on a Modern Warfare 2 sticker, and tossed in a free copy of the game. Let's take the Sapphire Radeon 5830 1GB for a spin and see how it stacks up against the competition.
