3dfx Monster PCI 4mb voodoo card.It has input/Outputs for sli !!! If you can find or own one already it can be linked together for retro sli mode.I used it in my retro build to play win98se versions of Blood with the 3dfx patch as well as a bunch of other 3dfx patched games.It was a flashback to the good old days when all these 3d rendering techniques were just in their infancy.These cards are selling for much more than I'm asking on ebay.I'd like to see someone relive the past like I did and have some fun with this old gem,comes with patch cord too.Asking $200 obo
