Well... the best is har to say... you want 030 if you want most compability with games... 060 is ofcause an upgrade to that CPU but you sacrifice compability so make sure you need the extra power.
I'd go with a Blizzard1230 or Blizzard1260 With SCSI kit, then have an external SCSI CDRW (or better yet a small SCSI tower for both CDRW and HDD for much speed improvement over any IDE HDD solusion).
