    Here are a few more quotes from extremely well
    known game makers about the Voodoo 3 and it's lack of

    Patrick Moynihan:
    I hate 16-bit rendering. It
    makes rendered scenes look like crap. Smooth gradations
    of color and light get broken up into visible
    patches and bands of color. This can be partially
    remedied by using a dithering algorithm to smooth the
    gradations when converting from the internal 32-bit render
    to the 16-bit output. But then you end up with a
    crappy dithered mess, especially noticeable at lower
    resolutions. The effect is less pronounced at higher
    resolutions, but still there. I love the speed of 3DFX's
    cards, but nVidia has proven (with the TNT chipset) that
    you can bring kick-ass 24-bit rendering to the
    desktop with incredible performance. Get with the
    program, 3DFX.
    Kick Engine's Martin:
    The lack of
    24/32 bit rendering is a major disappointment 3DFX now
    have the worst image quality of any of the major
    chipsets and are doing nothing to address this. There's
    more to graphics card than just it's fillrate. Also
    the maximum texture size is becoming a serious
    weakness and still no stencil buffer, I see. Also 32 bit
    internal rendering means nothing, if the source texture
    starts of in 16-bit colour, the output quality can not
    be better than the input quality. In fact, with
    multi-texturing the output quality will be far worse, more like
    12 bit quality. With a faster TNT on the way and
    cards like the Rage 128 and Permedia 3 coming, the
    Voodoo3 card looks very poor indeed. If all you want to
    do is play Quake2 at 60fps, then it's a good choice
    but for anything else, I'd give it a
    John Carmack, maker of Doom and Quake
    Voodoo3 will be in the ballgame with TNT, rage-128, and
    permedia 3, but it will be the most limited of the bunch.
    It will likely trade off somewhat higher delivered
    performance against the loss of flexibility. 3dfx downplays
    24 bit color because they don't have it. NVidia
    downplayed per-pixel mipmapping when they didn't have it
    with NV3. PowerVR downplayed bilinear filtering when
    they didn't have it with PCX1. Etc. If there isn't any
    blending or textures with alpha involved, the internal 24
    bit rendering (just like current voodoo cards)
    dithered into a 16 bit framebuffer looks reasonably close
    to a full 24 bit path. Blend a couple layers of thin
    clouds over an environment box and you will think you
    are back in 8 bit color...

    I dont know about
    you....but I am going to bet on the 32bit cards.
