HEY vineet.
if u r a serious gamer, u should stick with a crt. There are still developments which needs to be made on an LCD when it comes to moving pictures/scrolling text/gaming/moovies etc. LCD's are having lower response times when compared to crt's, and they normally perform better only in their native resolution.if the resolution is higher or lower, u may notice visual artifacts or windows. So if u r an avid gamer, movie fan, then stick with a CRT. Picture clarity of a CRT is also much more superior to an LCD. I myself have a laptop & desktop with Hitachi 19"CRT, so i can definitely feel the differences when playing games or movies in LCD's.
Ofcourse, SIZE,Power consumption, Heat, Radiation (though minimal) are the negative sides of a CRT..but as the visuals matters, i'm sticking to a crt for now.
