I doubt that the CD has the newer driver for the 3880. I would opt for the download.
It is very unlikely that the profiles need to be updated so if they are on the CD you should be able to use those. Another thread at present four down from this one
discussed location of the profiles.

Thanks for your input.
I sort of figured I will have to install the newer driver.
However if I remember correctly that the Apple Snow Leopard will find the newer drivers.
For printer profile I am hoping Ilford will add Golf Fibre Silk for the 3880.
Sent off an email this morning to them asking when to expect profiles for the 3880.
