Hi,
     I can't answer about Railroad Tycoon II, but for the other two, you
don't need a fast 3D card.  The way 3D add on cards work (such as VOODOO 2
cards) is through a pass-thru cable.  The card comes with a cable that you
attach one end of two the output of your 2D card and the other to the
output of your 3D only card.  It is possible to use these with a 2D/3D
card, you just have to tell the drivers which to use.  SLI works through a
ribbon cable that attaches between the two VOODOO 2 cards.
