dual channel memory is a must. As far as playing EQ2....i am beta testing it with an fx5200 card and it's really not good at all so I'd imaging your current card is definately a NO go. Even the top of the line cards like the 6800 PE and the Radeon X800 can't play the game with all the bells and whistles going. Keep in mind SOE is designing this game with next years top of the line specs in mind when playing it.
