is EQ2 DirectX based or OpenGL based, because if it is OpenGL based you might wanna get a ATI because they have better OpenGL support than nVidia.
EDIT: 6800 GT and the X800 PRO are basically the same price so it will be all good no matter what
And that 939 board is gonna be so sweet, because you know like in a couple years that mobo will still be good, because from what I understand that will become AMD's new standard and everything and it will be a snap to upgrade processors(if you want to of course)
