i know the c3 is 720p and is the one i want to get but if the U3 has like a lower input lag or like handles the graphics better ill get that one. cauz i will be mainly playing CoD and halo on xbox. also since most games i play are a little below 720 wouldnt there be less lag on a 720p tv than on a 1080p tv since its not having to down scale the resolution.
