Hey, I've had the Sony KDF-E42A10 for four or five years. I'd like to upgrade to a new LCD that does 1080p and is around the same size. My question is...is it worth it to buy one of the newer LCD's? Will I see a noticeable difference in picture, color, and clarity? I have been looking mainly at the X400,500 series, as well as the Sharp Aqous LC40E77U. Any advice is greatly appreciated. I will mostly use it to watch cable and play PS3 games.
