Not Enough? or Plenty?

I need this to be good enough for about 2 years. All i do is use it for World of Warcraft and Wildstar. no business use or anything. Utube and twitter etc is all i do.
I can afford more only if really needed.
no multiple monitors, no 3D, nothing special. I do want 3TB of space for movies, music etc.
