I have a PB 12" 1.33Gz with 768Mb of RAM. I have been playing with some scanned pictures (equivalent to 11 megapixels) and with some Nikon NEFs from a Nikon D2X (12 megapixels). I am using 10.3 and Photoshop CS2, CS2 already pushes the PB quite a bit and with this images if does quite slow, specially with the high megapixel NEFs (it works well with 6mp NEFs). Does it work any better with the newer PBs? Would more memory make a significant difference? (opoening a 50Mb image with 768Mb of RAM should be enough) anybody using a DX2 and a powerbook?
