Boxing vs. Krav Maga Question?

Hi...........I am signed up for boxing on a year commitment to a pretty good place but the thing is I've been really getting into psychology and think I wanna do that. I just turned 21 and sort of grew out of my mixed martial arts dreams. Future dreams of being a mixed martial artist was the only thing that deterred me from Krav Mage which I had been told would beat a mixed martial artist in the street but not in the ring. SO my question is how dose boxing compare to the striking in Krav Maga. Will a boxer have to forget everything he knows and relearn a whole new system or will the year of boxing put me ahead of the game when trying to learn Krav Maga? Is boxing that different fro the striking aspect of Krav?
