Sapphire Radeon HD4850 Review
 

There's always been a constant struggle between ATI and nVidia, and sometimes it's felt like nVidia's only been pulling farther and farther ahead since AMD's acquisition of ATI. However, ATI has not only come back with the release of the new RV770 GPU, they've also managed to heighten the competition, pushing nVidia to lower their prices. The RV770 is built on a 55nm manufacturing process, which should provide better performance at lower temperatures.

Sapphire supplied us with one of their initial Radeon HD4850 videocards, which features 512MB of GDDR3 memory, CrossFireX support, and is probably one of the fastest cards we've looked at yet. The Sapphire Radeon HD4850 promises cutting-edge performance, but incredible multimedia processing capabilities as well.
