HOLY %(!!! I just got a new TV ( I play on PS3) and before that, I was using a computer monitor. Yesterday I got an HDMI LED TV with 1080p and WOW!!! I can't belive the difference. It was like a whole new game to me. So much detail I have missed out on. Thought it was great before but now phenominal!!!
What kind of crappy monitor were you using to play Skyrim? Personally using a good 24" monitor that displays 1920x1200. That meaning 1200 is over 1080. Its colour calibrated as I also use this monitor to colour correct film footage. Add to that the high res texture pack. Played on a decent TV, and also got a manager of a local electricals store who loves TES too hook Skyrim up to the top range TV there, just doesnt seem as sharp or colourful. As someone mentioned earlier, TV's normally display in 720, even when they advertise 1080p, it just means it can display it, not that it is actually showing the full 1080p. In fact majority of TV is still displayed interlaced. So again, what monitor were you using?
Also with headphones, dont buy by fad, for example Skullcandy or Dre beats. They are cheap produced then marketed as high end. Get Sennheiser, or BOSE, or Sony MDR's, you get what you pay for. I have some Sennheisser hd595 cans and I can wear them hours on end. Not to mention the sound is incredible. Sound cards are also fantastic. Try before you buy if possible.
