Anybody running two dual head matrox pci cards. Pricewatch.com has G450 cards about $100 a piece. Two pci cards equals four monitors. If this kind of setup would work, why bother paying the big bucks for a four head card. Separate cards are cheaper, if one fails it's cheaper to fix. Only downside is a lost pci slot in the motherboard. Am I missing something? Thanks for the input.
