Would you invest in a better PC for a next gen sims game?

I've upgraded several times for The Sims. With the still-hypothetical Sims 5, however, I would want to see what 'improvements' they make to the game before buying it, let alone dropping a couple thousand dollars for a new computer. (I also wouldn't assume that those who have a top-end computer wouldn't need to upgrade in another two or three years.)
