I pre-ordered the game to download from my Orgin account. Will i have any problems running the game on my Alienware M14x? What are the minimum specs for the game?

No, you will not have any problems running the game. I don't know whether a nVidia 650 mobility will make the game look too good, but yeah, it'll run and I'll bet it'll run decently at least with fairly good looking settings.
