Sapphire Radeon x1800 GTO

"The Sapphire Radeon x1800 GTO uses the R520 at 500Mhz and has 256MB GDDR3 memory running at 1000Mhz. The Sapphire Radeon x1800 GTO has a 256Bit Memory Interface, 12 Pixel Shaders and DirectX 9.0c."

"The Sapphire Radeon x1800 GTO puts in a great performance using synthetic benchmarks beating the Sapphire Radeon x800 GTO by 21% and the Sapphire Radeon x1650 Pro by 23%. I was not surprised by the close performance between the Sapphire Radeon x800 GTO and Sapphire Radeon x1650 Pro because the Sapphire Radeon x800 GTO couldn't complete all of the 3dmark 2006 game tests."
