FWIW I did upgrade my Power MAC's superdrive to a 40x CD/DVD burner. It may have slightly increased the import speed, but not by much. I do enjoy being able to burn disks for the car in seconds rather than several minutes though....
It seems most of the time my computer spends on importing is in checking the data (I just redid all my CD's in AIFF so not compression was used) I found good condition, clean disks import MUCH faster, even on my older drive than dirty or scratched disks....
Now, for my opinion.... my drive cost me $79 6 months ago, and does lightscribe as well, which is pretty cool, so if your drive is slow (10x) I would recomend you do upgrade, if not for the faster read times, which you might see some benefit (for me, burning in 600+ CD's, I was out for all the speed I could get!) to be able to quickly burn car disks, and possibly to add lightscribe... though the disks for this are more expensive..
