Tweetabsolutely. get the hdmi cable. they're not that expensive. get a short 4 or 6 footer, shouldnt' cost more than $50 bucks depending on the brand. in my opinion the picture quality is much better than the regular cables. i dont think you absolutely need it for ps3, but if you're going HD, might as well go all the way, imo. i have a 42 pioneer on the wall with 1080p. awesome awesome awesome picture. when watching some of the nba games, i swear the sweat off these guys will drip down on my floor, crazyness
