we evaluate a somewhat unique Radeon-based graphics card, the Sapphire Radeon HD 3870 512MB Toxic. Unlike most reference 3870 cards, the Sapphire Radeon HD 3870 512MB Toxic differs from ATI’s reference design and features higher GPU and memory speeds, a fancy single-slot cooling solution that leverages Microloops’ Vapor-X technology, and it has one of the better retail bundles we have seen in quite a while too.
