Well as long as you have a CD drive and appreciate that the computer may be slower after the install then go ahead. Personally I never bothered with 3.9 but then I'm an old fuddy duddy. Also my Amigas never had the grunt to cope with the OS and just ground to a halt. I give you a link to my page showing you the day I installed OS3.9. I have machines with OS3.9 on, like the A4000T and a towered 1200. However I still use OS3.0 to be honest.
Anyway have fun and make a backup. I simply copy my Workbench to a folder on my Work partition. That way if it goes belly up you can always just copy the whole thing back.
