I am considering the purchase of a computer combo kit from either Newegg or Tigerdirect. Some of these kits come with AMD APUs (A4, A6, etc.). Others come with AMD CPUs (ie, Athlon X3). I'm looking at AMD because they seem to be somewhat cheaper. I've been trying to understand the differences but the only thing I almost understand is that the APUs are accelerated and have both CPU and GPU on board. For a low middle-of-the-road general purpose computer (not a gamer) is one any better than the other?
