Apple made a hash of some of their 2x/4x agp slots by combining adc
connections within them - the connections they used should have been unused
and reserved for future improvements to the agp spec. When these 'reserved'
connections came into use with 8x agp apple had to redesign the agp slot for
the G5 and called it agp pro - effectively killing any backward
compatibility for a G5 mac edition card in a G4 - it won't physically fit.
And flashed 8x capable cards need the tape fix to isolate the adc pins in
the agp slot.
I have never come across a 4x agp 9800 pro specifically for a G4 and it
probably doesn't exist as the apple spec lists the best card for a MDD model
as the 128 Ti.
However the pc versions of the 9700/9800 pro and even the 9800 XT will
all physically fit and work comfortably in the G4 range when flashed and
taped. Though some care should be taken with card/slot compatibility as the
universal 2x/4x/8x connector on the card has two notches - whereas the later
4x/8x connector has only one and will not fit in the earlier G4 models with
2x agp like the cube and sawtooth etc.
