Maximum PC: The Devil is back, and this time it's in the form of a Radeon HD 7870 graphics card. Powercolor first summoned the Devil to power its dual-GPU Radeon 7990 part, a hellacious card that's almost as fast as two cards in SLI. This second member to Powercolor's Devil family of graphics card isn't wielding multiple GPUs, but it is equipped with an elaborate cooling solution similar to the Devil 13.
