Hi guys, I have been given an early G5 Powermac (one Ethernet port). I bought a 20" cinema monitor to use but since realised that the port on the current card in the unit is DVI. Aside from the very expensive DVI to ADC converter, could I just buy a new AGP graph card like the NVidia GX5200 with ADC or are there issues with that? Or are there better cards to be had instead? Thanks in advance guys!
