That's actually a single Voodoo2 card. The 3 chips are what make up 1 V2 chipset. 1 is the PixelFX2, and the others are a pair of TexelFX2 chips so it can do single cycle multitexturing or trilinear filtering. An SLI setup would be 6 chips.
That also appears to be a card with 8MB texture memory and 2MB framebuffer like the one used for Gauntlet Legends/Dark Legacy.
