For HIARCS 7.0, the G3/400 is not only faster than a Pentium 450, it is
faster than a Pentium II/550 would be.

I base this on my 2.5 hour HIARCS benchmark test (average of 33 of the LCTII
positions for 4.5 minutes thinking each - see full table at end. If any
of you HIARCS owners pick up a Pentium III/500 (or 550), please let me know,
and I'll send you the benchmark. I'd love to get some stats on the PIII.

If you really want some serious horsepower - there are G3/466 CPUs available
for upgrades now. Think "Pentium II/640 MHz". And, when plugged into
the newest G3's, these run at 550 MHz (presumably no guarantee they will
work on all of them). Think "Pentium II/766 MHz". And you can buy one now.

?! There are more chess programs available for the Mac than even I am
   willing to spend the money to buy. See

 HIARCS 7.0 is the only top-tier SSDF program available for the Mac.
 Of course, it's at the top of the list, and runs faster on the Mac than
 on the Pentiums, so that's not too bad. But, I'll grant you, the depth
 isn't there. For the chess utility programs (things other than chess engines)
 if there's anything you want that isn't on the Mac,
 SoftWindows on the Mac seems to work just fine - I've used Chess Mentor,
 Gromit, Chessmaster 5000, and others under SoftWindows. But for chess
 engine analysis, SoftWindows is a drastic drop in horsepower.

 Other commercial chess programs available for the Mac are:
 - Chessmaster 4000 (probably 180 points weaker than HIARCS)
 - Sigma Chess 4.0 (probably even weaker, and the freeware version above
     makes purchase marginal, but it is fantastic as freeware).
 - Virtual Chess (but France is the only place I've found where you can
     actually purchase it).
 - Checkmate ( not very strong, but allows modem play, vs. BattleChess, too).

It sounds like, by "chess programs" you intend "chess playing programs",
as opposed to:

Chess Databases
   ExaChess
   SmartChess
   Essentia Mac
   Bookup Mac
   ChessBase Mac (if there are any copies left - they've stopped production)

Chess Tutorials
   Chess Mentor Mac
   Maurice Ashley Teaches Chess (Mac)
   Chess Mates
   Dr Schiller Teaches Chess

Chess Tournament pairing programs
   (forget the name, but it is on the list)

> while Mac Chess 5.0 and Crafty (Mac version) are available as freeware.

Also, Sigma Chess Lite 4.02 is very nice.

There are lots of others (GNUChess, RChess, Chess++, TSCP, and a couple
of shareware ones, but they don't come close to the Crafty/MacChess/Sigma
programs).

>I'm not sure how strong Chessmaster 4000 for the Mac is.

  About 180 points less than HIARCS 7.0. But boy, can it see checkmates!
  Too bad about the interface. Yechhh.

The SSDF folks did say they were shopping. The K7 sounds like it might
be worth waiting for. For HIARCS, anyway, the AMD machines seem to do
a bit better than the Intel chips.
