well, they're fast enough at floating point for almost anything, esp. the
K6-2 series, which adds some new floating point wizardry that the original
K6 does not have.  In any case, they've always been better than the Cyrix
6x86, at least.  The upshot is that I can use xmame under X11 at 16bpp
now, whereas before I had to use 8bpp since 16bpp was too slow.  And
compiling stuff is really fast :) .. But I suppose for scientific
computing/what have you, the fpu speed is probably more important...
