DualGPU systems are very trendy in recent time and whole story begun with ATi "Gemini" project. Idea was born long time ago, when two graphics processors were integrated into one graphics card, but that idea didn't get much popularity until now. On the other hand, ATi Radeon HD 3870X2 turned out as accessible to most users and at the same time very powerful solution. So all doubts in making investment in such card can be shattered in pieces.
