so i called the apple store and they said they don't carry one. i have a 1.8 dual G5 by the way. i already have a vga monitor going into my DVI input..now i want to add another VGA monitor..but i only have the ADC slot left. so i would need a ADC to VGA adapter right? will this work? i just can't afford the new apple displays yet.. please help.....
