Asus is no longer the only graphics vendor offering a Radeon HD 5870 videocard with 2GB of RAM, twice the amount of ATI's reference design. Sapphire has joined the oversized frame buffer party with a 2GB card of its own.
In addition to doubling up on RAM, Sapphire's HD 5870 Toxic Edition card comes factory overclocked to 925MHz on the core, a respectable boost over the 850MHz reference design. Sapphire also goosed the memory to 1225MHz (4.9GHz effective), a small bump over the 1200MHz (4.8GHz effective) reference design.
The card also comes with Sapphire's Vapor-X heatsink. According to Sapphire, you can expect better cooling with a "virtually silent gaming experience," giving you the best of both worlds.
