I am currently trying to decide what mac to buy. My Choices are either the new 1.25GHz 15"AlPB, or the DualG5. If I go for the G5 I can't afford to buy another display, so I was wondering if I can use the LCD I already have. It's not got an ADC connection, but can I use the secondary connector on the graphics card (DVI) for the primary display? I realise I could buy a DVI to ADC converter but don't see why I should have to.
