Well, I won't argue over 30%.  But that list is *no* good.  For several reasons:

1.) DB was _never_ intended to play other computers.  EVER.

2.) This is on *CURRENT* HW.  Ever try to use Shredder 6 on a Pentium Pro 200?

3.) There is a HUGE thread below this one, about Fritz 5.32 being *much* better
than Fritz 7.
