OK so it is not worth selling my AGP powermac G5 (and its one of the fastest
machines that can run OS9 in case I want to do an NN piece someday) so I am
finally upgrading the videocard. These are the two choices in the budget:

ATi Radeon 9800XT VRAM : 256MB 256-bit DDR
OR
Mac nVidia Geforce 6800 GT 256MB Video Card G4 G5 AGP

Which would be a better jitter performer?

Thanks,
Christopher Overstreet
