...I don't wish to imagine how would it be doing modern computing on PPC turbo board from 1997, connected to a computer from 1992, but for the fun of doing it, it is acceptable.
I have probably the fastest CSPPC board over the world. (604/400MHz with 060/66MHz). Believe me it's really fast. Enough fast for use every day

For example, CPU 68k&PPC speed test by SysSpeed:
For 68060/66MHz:
MIPS - 86.53
MFLOPS - 32.62
For PPC 604e/400MHz:
MIPS - 581.89
MFLOPS - 400.01
UW-SCSI SCA 36GB with SFS:
CreateFile 22.59 MB/s
WriteFile 28.45 MB/s
ReadFile 24.98 MB/s
RawRead 28.74 MB/s
Looks very nice isn't it?
So I think the new OS4.1 for my classic Amiga will run on it smooth enough
