Using TV to replace monitor for gaming...

Hi,

I have a 7 year old Dell Dimension 8250 which I recently upgraded primarily for gaming...I'm using an nVidia 6600 GT video card...no problem running the game(s) I play, it performs well...

In reviewing the manuals and specs it says that this computer has "TV out" capability...I'd like to experiment with replacing my monitor with a TV, primarily to have a bigger screen for gaming...

Has anyone done this...?...How well did it work...?...did you lose FPS...?

Most importantly, I've looked over the computer and am uncertain what sort of cord or adapter I would need...any recommendations, brands, specific products...? The TV I would be using has the standard red/white/yellow video/audio feed ports...

Any input/advice is welcomed !

Thanks
