This has a Radeon 3200 graphics processor built in. I was able to play some pretty stout games on this GPU (at low levels) on my kids computer. It should be able to do home theater if you ever decide to go that route.
Good price.
Never used an Acer box, though. Most of my stuff is Asus, Gateway, or Toshiba.
Always had very good luck with the Asus stuff.
