text: i generally know what the different parts of a computer do, but i don't know if this upgrade is worth it? 1.83ghz intel core duo----or----2.0ghz 512mb (single sodimm) 667mhz ddr2 sdram---or---1gb 80gb 5400-rpm serial ata hard drive---or----100gb ati mobility radeon x1600 with 128mb gddr3 memory---or---with 256mb gddr3 memory ------------- my wife wants to use this for photos, videos, scrapbooking...so lots of photoshop or iphoto stuff.  we have never owned an apple product, so we don't know if we should spend $500 to upgrade.  i am not sure if we will be able to tell the difference.  i put the upgrade after the "---or---".  which are most important for photo/video work she wants to do.  thoughts? hi,  because of the much photo and video editing. i highly recommend you buying the laptop with intel's core duo. (core duo- is like have two cpu's instead of only one) -the more gb of ram the better. -hard drive i would also go with the bigger 100gb because it's stores a lot more pictures than the 80gb -the ati x1600(video card- if you're a very serious gamer than go with the 256 mb version if you're not a serious gamer than go with 128mb)  let me tell you why i recommend you the duo core instead of the 2.0ghz the duo core is right now intel's newest cpu.the duo core was specially made for giving consumers a lot more performance for video editing,photo editing, autocad and lots more. now by having a duo core what used to take you perhaps an hour to make(video editing), now will take you about 40min.or less. so it really is a big improvement.
