I am currently looking to upgrade and could use some advice on the BTO options. I am looking at getting the new dual 2.0ghz powermac. I primarily use my computer for Photoshop and image browsing. Aperture is not something that interests me at this point. I currently use a 1ghz TiBook which doesn't owe me a penny but is starting to seem slow. What benefit would the 7800 GT card have for me if I dont really play that many games? Does it have a noticeable improvement on graphics programs?
