I dont know about anybody else but:
I got a new Goodmans 32". - I tried it on 1080i first and didnt think there was much improvement, especially on GRAW it ran slower and the graphics looked like they had been toned down in some places. I then tried 1080p which was even worse. Im now running it on 720P which runs really smooth and everything looked brilliant and even better than that, nothing had been toned down.
The Goodmans is an incredible TV for the price by the way. I might make a thread with some pics if anyone's interested.
