Gotta love dem DVD install speeds but yea, the 5gb patch does suck! It is usually why I buy the steam version because it installed virtually everything in the pre-load including the patches and stuff and all I had to do was unpack it which didn't take too long.
But hopefully, the wait will be worth it for you when you start playing the game!
