Not really... AFAIK, Crossfire is a system of linking two CARDS together - not two GPU's. "Quadfire" would be having four 4870 x2's linked together... It's like a motherboard - If a motherboard can support dual core processors, it doesn't mean it can support two actual processors.
I understand where he is coming from. But, Crossfire and SLI is multiple GPU's, not cards. You can't Crossfire CARDS. Only the processing units on them. If there are 2 GPU's on the card. It's technically and by textbook definition, Crossfire.
