On the 15" PowerBook model, which do you think is the better buy? For my specific purposes I mean that I can get the exact same specifications, except for the processor, for about a $120 price difference. Basically what I'm asking is if the extra 170MHz is worth $120 plus tax (7.25%). I know that there's only a marginal performance difference noted so far between the two (9-11%) but I'm interested in real world performance users that place a pretty hefty demand on their systems (database, pretty intense rendering, limited DV and GarageBand action). How easy is it to tell the difference between these two processor speeds? Are there any thermal considerations for the faster processor (lower battery life, more heat)? Also, as a somewhat unrelated question, how much better is the 128MB GPU? I'd have to go for the faster processor in order to get this, but since most of my non-Photoshop graphics work is CPU-intensive rather than GPU-intensive, I'll only pay the premiums if any developers think that CoreImage performance will be dramatically better with the double graphics RAM. Are there any clock speed or specification differences between the Mobility 9700 64 and 128 versions? Lots of questions, I know, but any feedback or input you could provide would be great. I'll be ordering my new PB within the week! Thanks all.
