Ultimate is a waste of money imo.
Way more money for not much.
You could get a 3 pack of OEM Premium off of newegg and save a bit of money i bet.
I vote for that.
Unless you absolutely need retail.
If you buy the Utlimate version you can each additional Premium versions for $50 each!
So, it might work out this is the cheapest route to get 3 retail versions.
