I read around the net, that using large TV LCD setups(any) are not that great for 3dcg. Game consoles and such work well on them, but nothing can touch a good 22-24inch widescreen computer LCD for graphics(unless you do dual monitor). For the price of that 42inch, you could probably do triple 19inch monitor setups(their fairly cheap now), which as soon as you view triple setups for games OR graphics, you'll never want anything else, lol(including high end projectors). As for a graphics card, a Nvidia 7600 to 7900GT should do fine for anything out now. (Btw this is just what I read, not an opinion, except for triple monitors)
