I'm planning on getting a core i5 processor because it falls in my price range. I will use my laptop for downloading large files, burning music/videos, web design (dreamweaver/flash), and maybe some light gaming. I tend to run 3-4 programs at once. some processors I am interested are i5-430M 2.26GHz Turbo Boost up to 2.53GHz i5-450M 2.40GHz Turbo Boost up to 2.66GHz i5-520M 2.40GHz Turbo Boost up to 2.93GHz will it be worth spending the extra $100 to get the 520m? and will i see a noticeable difference between them? or should I not go with the i5 and chose another type? any suggestions are appreciated.
