Depends on the game really if it wants me to just explore its world and enjoy it then graphics are quite important I wouldnt have enjoyed Oblivion anywhere near as much if it wasnt for the pretty graphics although I would say art direction is always more important than graphics.
Usually though I really am not bothered by dated graphics just the weekend gone I was playing Legend of Zelda a Link to the past for example hardly stellar graphics but its got a great art style so things dont get blurred same with Secret of Mana which I also played recently I also regularly play Punch Out from the NES days (virtual console for this one) and its still perfectly playable same with FFVII and Baldurs Gate 2 great games that are still fun to play despite not looking great by todays standards.
I will admit that good graphics rarely if ever hurt a title though but in most games they take a back seat to other factors i.e story, gameplay etc while of course text adventure games dont really need graphics at all.
