well on my 52" sammy 750 it is incredibly awesome at 1080p 120hz/ crystal clear/
but i found it way 2 hard 2 game on bcause i had 2 move my eyes around 2 much 2 see the whole screen at about 4'/
and when i sat further back about 10' it was harder 2 get into the game
so i got a 32" sammy 550 and a wall mount and moved gammin comp into spare bedroom / office gammed on it abit and im luvin the 32" 4 the comp

/ very clear and easy on the eyes 4 internet 2
if it mostly used 4 comp i would suggest a 32" max
