I curently have a dual 2.5 and am wondering what you all think of going up two hrz to 2.7. I can sell my g5 right now to have enough for the same model with a difrent video card. I curently have the 6800 to run my 30 in cinema. Should I sell my 2.5 and get the 2.7 with a smaller card and faster processor? Im just doing high photo editing.
