I am planning to buy a new Macbook this week. I am going to upgrade the RAM and HD myself, to 2GB and to a 200GB 7200RPM hard drive (sell the stock parts on Ebay!). Is it worth the extra cost to bump the processor to 2.2? Again, HD size difference is not applicable. I will be using Adobe Photoshop for photo editing. Other than that, just basic internet browsing, online video streaming, email, etc. Thoughts?
