Most people who think they are getting a deal dropping $300 on an HDTV probably aren't hardcore gamers and likely to notice. There's a long laundry list of things that the vast majority of gamers won't notice directly that can affect gameplay.

But that doesn't stop people from ending up in that situation. However, one mitigating factor is that if you are buying those super cheap TVs, it is likely that you don't own a 360 or PS3 either.
