Ghosting is not a problem now, Games and DVD movies are excellent on TFT's.The fact that you also do not get any reflections at all with them is one reason that many gamers are now using them.
I think only the really dedicated gamer would find a problem in the sense that they like to change their resolution to match the game, TFT's work best at their native resolution.
I also think you will really need to try one for yourself as both types of monitor have their advantage/disadvantage, and only you can decide which is best for you. Good luck with your choice, take your time deciding as it's a big expense to find you have made the wrong decision.
Mine? I use an AOC LM720 17" TFT, and love it. j.
