Simple Questions - April 25, 2015

I've posted a ton of different builds and each time they get outdated within a few days because something goes up like $50. I think I'm finally about ready to order, though, and I have a couple of questions. Is 500W enough for this, and would downgrading to a 4460 be a bad idea? Plan to use this for gaming, and right now I have my eyes on GTA V and Cities: Skylines (which is apparently a very processor-hungry game). I have no intentions of overclocking.
