Considering he doesn't have an HDTV, I don't think he needs either one right now. He could buy one now if he plans to have an HDTV in the near future. He won't have any use for HDMI, upconverting, upscaling, or HD audio processing at this time.
I know you are trying to help, I am not intending to be rude. I am simply making sure the OP knows what he is dealing with.
I hope there are no hard feelings, I have no hard feelings toward you.
