I am installing V2 SLI and I would like to know if I still need the regular video card in addition to the 2 voodoo2 card. iam unclear about this dont want to make any mistakes

Sure. Voodoo II is just an add-on card. It can be, however, used to work as a display adaptor with the Legendgraphix drivers (link available in a section above), but you still need a primary 2D card to make a setup. Just make sure you downloaded correct drivers (for mismatched boards if they're of different brands - see: Koolsmoky's driver for Obsidian boards topic in the previous section)If you're running Win98, the regular FastVoodoo 4.6 from this site will be OK.
