So , as the title says this year I want to buy me a smart tv. I don't usually look at any program but my wife does and I want one for my living-room. So , my mind is a little set on Samsung. But what are the letters infront mean: As example F6400 , UE8000, US 8000 , etc etc ... with model should i chose ? Is the 3d part any good ? can I use it with my nvidia card to simulate a 3d game ? please let me know as in romania we buy a tv for more than 3 - 5 years. Money does not grow on any tree here !
