I have an old latitude d630c with 2.4ghz Intel core 2duo, 120gb 7200rpm drive. I use it for standard Internet, movies and word processing but my primary use is Photoshop and Illustrator. I have Adobe Studio CS6. I am on a budget so I was looking at refurbished laptops. I want a 1tb drive but all of the affordable refurbs I have seen have 5400rpm drives. Surprisingly my old laptop isn't horrible for my graphics but I need better. Will more drive space, ram and a quad core processor make up for the 5400rpm or will I not notice because what I have now is just tolerable?
