The ATI Radeon HD 4870 graphics card arrived back in June with same-day Linux support through the Catalyst driver and there was even open-source mode-setting support. We have been very pleased with the level of Linux support for the Radeon HD 4000 series and it continues with features such as UVD2 and XvMC out on the horizon. With a few months having passed since the release of the Radeon HD 4870, we are starting to see more innovative RV770 products from ATI's partners. In August we looked at the Sapphire Radeon HD 4850 Toxic, which was a factory-overclocked Radeon HD 4850. Today we are looking at the Sapphire Radeon HD 4870 Toxic, which takes the original Radeon HD 4870 to the next level with heightened frequencies and an exclusive Vapor-X cooling solution.
