This is a card that supposedly never made it off the drawing board. It will be interesting to see it in action. This card supposedly offers no penalty AA. (The V5-6K made a similar false claim)
There have been a few of these floating about, the problem was that the board wouldn't fit into many cases, and was looking at about $800 retail price. Only a few boards got out, and even fewer went up on ebay.
nukes you are thinking about the Voodoo 5 6000, which had 4 VSA-100 chips (at 166MHz each with 32MB memory to itself). This is the 3dfx rampage which was supposed to follow the Voodoo5 series.
