Very simple math will tell you if the upgrade is worth it:

If you manage your breeding times so that you waste little time not breeding (like, breed long hatchers overnight) then in one month you can breed 720 hourse worth of dragons. 20% savings is 144 hours. This is equivalent to spending 144 gems over that month. You will recover the cost in 4 months for the cave upgrade and in 9 months for the Island. Realistically you will miss some breeding time, so multiply the figures by 1.5 or so and you will be right.
