I also replaced my Voodoo3 with a Voodoo 5 back when I had an A4000 with Mediator. I found it was unstable and when it did work it was slower in benchmarks and in Quake than the Voodoo3. I think Elbox's drivers leave something to be desired. I went back to the Voodoo 3 and the Voodoo 5 went to eBay.
