Depends, if you've got anything better than a Geforce2 MX installed, forget the Voodoo3!
I upgraded from a Voodoo3 to a GF2 MX years back, and then, the GF2 seemed soooo fast!
If I put the same - GF2 MX - card in my pIII 667 machine ,(Which currently houses my old GF4 MX440,which itself replaced the GF2 MX) Fs2002 is reduced to a very stuttery experience. Thus, I would'nt expect great things from the Voodoo3.
It should cope with conservative ,i.e. low, settings, but I would'nt expect too much.
I think, thinking of a strange way to destroy the Voodoo will ultimately prove more fun!
(Well, it was free was'nt it? )
Consider the Geforce FX 5200,which are 128MB and fully support DX9 - the Voodoo3 is a 16MB DX7 card I think!
These cards now cost under 40quid, I'd save myself a lot of grief and install one of those instead, it should be quite happy with the pIII yet will be great on anything faster, and are still fully supported, something the Voodoo's are not.
