The HD3870X2 is not your average video card. Instead of creating a single GPU with the power to compete with the 8800Ultra and beyond, AMD has chosen to go the multi-chip route instead. The HD3870X2, just as the name implies, simply is a card that has two HD3870 GPU's. It is not the first video card in history with two GPU's. The ATi Radeon Rage Fury MAX is one example and we all remember NVIDIA's first attempt, the GeForce 7950 GX2. Recently AMD tested a similar design with the HD2600 Gemini cards which were a very rare sight in the wild. NVIDIA is also working on a multi-GPU card that should be out pretty soon.
