Red-
although you are an exert in the field and your new 4000 atx boxes with pci sound exciting, a Voodoo card is NOT a Zorro III video card obviously.
To answer the question the best Zorro card is Picasso IV - also the original Cybervision 64 is very good as well.
And to be more accurate about the Buster issue - it is best to have Buster 11 but you can be OK with Buster 07,06 or even 09 its just that certain High end cards wont work at max speed sometimes or not work at all in the case of one or two of them.. but most systems will be fine with these.
