ok I will explain, LCD is for GAMING LED is for watching movies and Plasma is Home theather which is 90% for MOVIE not gaming you can use for any but that's best for movie and sound I have LCD because I don really watch Movie just play HD gaming well that's my thoughs so..my answer is if you play games then you must buy HD 1080P LCD
£700 for a Samsung 46" 1080p 100Hz LCD. This is good enough for me I think. =D
Theres so many factors to consider it gets quite hard to compare sometimes.
Luckily I have the advantage of being 'young' and can help my parents with this stuff.
