On video, I'm not a gamer, but would like to own a dual HDMI out, with sound, to mirror two tvs/monitors with 1080p/i capability. I watch webcast sports and send it to a larger tv. DVI to HDMI is not good enough, no sound.
When a monitor is considered, I just purchased a 24" tv(32" would not be too big) to use as a monitor. With the right video card, It would be great. The sound will never be as good as separate speakers though.
I am trying to reduce the mess of wires that are used under normal circumstances. I am using a wireless logitech wave keyboard/mouse combo and the tv's speakers for my main system (less wires). Since I generally have at least two systems up and also have a tv/dvr/vcr/dvd pile all in an "L" configuration, I produce a rat's nest of wires.
Except for the video card, I guess this is all "add on" stuff..........but you have to do that too.
