imho crt's are way better then lcd for gaming, resolution wise, and the lcd's normally have a wait time on imagery; if you arent limited by space go crt you can get bigger, great dot pitch, and wont be disappointed. only benefit i've seen for lcd's is for a small workspace.
a 19 inch even 21 inch is comparable in price to a 17 inch lcd, and the crt can do way higher (1600x1200) res's
good luck to you in your search
