"Connect3D Radeon x1950 Pro review also featuring Sapphire Radeon x1800 GTO. The Connect3D Radeon x1950 Pro is the latest mainstream video card from ATI featuring the powerful R570 GPU which has 36 pixel shaders and can deliver 44GB of bandwidth!"

CONNECT3D RADEON X1950 PRO

"The world's fastest consumer GPU The Radeon X1950 conquers the competition with brute force and massive parallelism, including an ultra-threaded engine, high-speed memory support and 90 nanometer technology."

"Enter a world of visual velocity Prepare your rig for the future of games with the Radeon X1950 series the fastest consumer 3D graphics processor on the planet. With its ultra-threaded engine and unparalleled shader performance, the Radeon X1950 delivers maximum graphical detail at incredible frame rates. Then go beyond games with Avivo video and display technology and watch HD movies and digital photos come to life."

"The world's fastest consumer GPU The Radeon X1950 conquers the competition with brute force and massive parallelism, including an ultra-threaded engine, high-speed memory support and 90 nanometer technology."

"CrossFire : Multiply and Conquer with Multi-GPU Performance Designed from the ground up with GPU sharing in mind, the Radeon X1950 series allows you to get incredible gaming performance by adding a Radeon X1950 CrossFire Edition graphics card for ultra fast performance that works with all games, all the time. CrossFire's supertiling GPU sharing speeds rendering by evenly dividing the graphics processing, intelligently alternating the rendering workload to each Radeon GPU for efficient load balancing, and optimized performance. CrossFire ignites with the higher anti-aliasing, anisotropic filtering, shading, and texture settings you desire. Adjust your display configurations, experiment with your advanced 3D settings, and check the effect with a real-time 3D-rendered preview within ATI's CATALYST Control Center to rule your CrossFire system."

"Slide your graphics settings to 'V. High' The Radeon X1950 promises the world's fastest shader performance with Shader Model 3.0. ATI allows you to experience simultaneous HDR and advanced adaptive anti-aliasing for incredible enhancements to lighting contour and colour details, delivering the ultimate in visually immersive 3D gaming."

"Beyond games There's more to PC graphics than games and Avivo Video and Display Perfection makes sure you experience it all. Avivo promises a high definition visual experience, delivering sharper photos, smoother video, true-to-life image representation and universal display connectivity. High definition images come to life with remarkable clarity and over 1 billion colours."
