The above image is the ideal look, produced by cards with the 3Dfx Voodoo or Voodoo Rush chip, running under the 3Dfx own Glide engine. You can try whichever card you want, the image quality won't get better than that.

Running the Voodoo under the Direct3D engine shows that the quality gets definitely worse. The sky looks less smooth, the transparency of the fog is less than above. Other cards can do it better under Direct3D.
