The RAGE PRO TURBO PCI is a graphics card (GPU) developed by ATI (now part of AMD), which was part of the RAGE series of video cards. It was primarily designed for use in desktop computers in the late 1990s and early 2000s. The "Turbo" version likely refers to a higher-performance variant of the card, and the "PCI" indicates that it uses the PCI (Peripheral Component Interconnect) bus interface for connecting to the motherboard.

RAGE PRO TURBO PCI (DirectX) Windows driver refers to the software that enables the operating system (Windows) to communicate with the graphics card, allowing you to use the card for rendering graphics and running applications that rely on hardware acceleration. The driver package would likely include support for DirectX, a set of multimedia APIs (Application Programming Interfaces) that allow applications to interface with hardware like GPUs.
