Voodoo 5 6000

From IexWiki

The most anticipated card in 3D Gaming history, ever. This card was about over a foot long and had 4 dedicated GPUs. Supporting (reportedly pretty buggy) 8x Anti-Aliasing, basic AGP support and was supposed to be 3DFX's answer to NVIDIA's GeForce 2 GTS. Unfortunetly the company went out of business before the card ever made it to the market. A few prototypes have been salvaged (somewhere in 300's range) and appear now and again on ebay for anywhere between $500-2000 and beyond, even for non-functioning prototypes.
