3dfx maybe gone, but it'd be interesting to find out where they thought they were going technology wise. Sure there was supposed to be "Gigapixel tech", but how was it used, performance estimates, etc.
Here's the digit-life article which was written with the assistance of someone working for 3dfx, but I never knew who. Wavey might know who he was.

And here is another one for which I have no idea who the source was either:

One mistake they apparently all make is the claim that Fear would have been a "refresh" to Spectre. It was to be a high end Tiler. While Spectre wasn't fully dx8.1 compliant (due to PS 1.0 only/lacking address ops), Fear would have been fully dx8.1 compliant.
Single chip TBR card with 4 pipes/1 TMU and the geometry processor named Sage II with 250M vertices/sec theoretical and 125M vertices/sec sustained. I don't think anyone could have come up with definite performance estimates as final clock speed wasn't even certain, but MSAA for free shouldn't be too hard for it, being a Tiler.
By the way the second link's approach explains quite adequately under which conditions Spectre would have had essentially free MSAA, that Dave already mentioned.
