Better stick with the PIV and use P96 with it. In terms of speed there isn`t much difference and you would lose the automatic scandoubler/sonitorswitcher of the PIV unless you have the scandoublermodul for the CD64/3D.
AFAIK the only ZIII Card that can outperform the PIV in 2D speed is the CV64. The CV64/3D is actually slower.
Is you do want to use the CV64/3D take CGX.
