Looking for some advice regarding the new 15 inch MBPs. I'm leaning towards the lower end option, since there is a $400 price difference but have a couple of concerns. 1) Main concern - only 256MB on the GPU. I am a pretty heavy iPhoto and iMovie user - but very little gaming of photo shop. Do you think the 256 is ok? I really wish there was a 512 BTO option. 2) Processor I don't think I'll see a huge impact between the 2 and 2.2 ghz processors. Anyone else think this is a big issue? 3) Hardrive - No concern plan to upgrade Comments and suggestions are appreciated.
