ATI plans to announce its Radeon 9000 line of graphics cards on Wednesday, according to DigiTimes. The line will consist of the Radeon 9000 and 9000 Pro, along with the high-end Radeon 9700, and will reportedly give Nvidia’s GeForce4 Ti a run for its money. It’s unknown whether ATI will announce a Mac version at the same time — ATI has traditionally delivered Mac versions of its products months after shipping the PC versions — although the company will be exhibiting at Macworld Expo New York.
