- But that isn't a matter of *WINDOWS* performance; it's a specific
- program. That's not what he asked about.

-
- The bottom line is that a math coprocessor does ZERO for Windows
- performance -- the bottleneck is generally video. Of course, that
- doesn't mean a coprocessor won't help some specific programs do things
- more quickly (spreadsheets, CAD, etc.); of course, that's independent
- of whether a program is under Windows or not.
