While the comparison is pretty impressive and shows about twice the speed for the Vampire against the 060/80 it also reminds me how slow 68k actually is. My Powerbook calculates the glassletter scene with the same resolution in 9s - about 16 times the speed of the Vampire and about 30 times the speed of a 060/80. And that without being native ppc code, but run by the Trance 68k JIT.
But I am really looking forward to the Vampireboard and may purchase one eventually. It'll be the fastest 68k system.
