I'd say that for the things you describe, you'd probably never notice the difference between the two.
My 7 yr old PowerBook 15 G4 is about to crash. It has been great but I need to replace with new MacBook Pro 15. Which one 2.0GHz or 2.2 GHz? Is the 2.2 worth $400 more?
I will use MacBook Pro as backup/substitute to iMac 24 plus I will use mainly for photos (very few videos), financial records (MS Office), Internet browsing. I will not need larger hard drive but not sure if I need more powerful intel chip or the stronger AMD Radeon HD?
Any suggestions greatly appreciated! :?:
