ATI Technologies introduced several graphics cards, including three that it says offer top performance at a low cost and two more that make up a new family of high-end cards. Three new Radeon cards, announced on Wednesday, offer the quality of ATI\u2019s higher-end cards including simultaneous high-dynamic range lighting and full screen anti-aliasing, but cost less than similar products, ATI said. The new X1300 XT costs US$89, the X1650 Pro will retail for $99, and the X1900XT will sell for $279. The cards can display 1.07 billion colors when used with 10-bit displays. ATI also introduced the Radeon X1950 series that offers very fast performance and high-quality imaging, aimed at serious gamers. The cards will cost $449. The X1950 can render fast frame rates at high resolutions or maximize image quality settings for users of mainstream resolutions. All of the new cards are supported by Catalyst, ATI software that offers gamers ongoing software updates for performance, stability and new features.Compatible with Microsoft\u2019s upcoming Vista operating system and capable of supporting high-definition formats, the cards are meant to improve images displayed on PCs from games, DVDs and photos. Both the new low-end and high-end cards are expected to ship on Sept. 14.-Nancy Gohring, IDG News Service (Dublin Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
