Thanks for the replies. I am interested in keeping up with Apple technologies but want to resort to the used market. I thought the G5's were a robust machine at a steal these days, but it seems that C2D and above are just smoking by your reviews.
The only caveat is my older legacy software...but I can definitely keep my G4 and below systems!
PS: Can G5's boot into OS9? Not run classic in OSX, but reboot with OS9 system folder?
No they can't.
