motion video card hacks? ok, i got a g4 dual 1.42 fw 800 model cpu. i have 2gb of ram and i just upgraded the graphics card to the gforce ti 4600 with 128MB of ram on it... now it seems that only 5 cards will work. and even worse the card i can get is a 9800 pro with no adc --- so what the hell do i do with my 20in cinema display i just got in jan????
