How Much Will A Lcd Tv Effect Your Power Bill?

I have a xbox 360 elite and i want a new HDTV. LCD seems the best but i hear it hikes your power bill. Is it true? any recomendations on TVs. Im thinking a 27 to 32 inch.

Will Using A Lcd Tv (sharp Aquos 42″) Effect My Gameplay In Crysis?

My Spec r :
Intel Core 2 Duo 3.0 Ghz
Galaxy 8800GT (overclocked edition)
2GB RAM
Windows Vista Premium 64-Bit
500GB Hardrive
(oh and will CRYSIS still look pretty?)
