I'm currently looking at buying the new-gen MacBook Pro 15" but am unsure whether I should go with the 2.4 Ghz, 256 Mb nVidia, and 4 Gb RAM or the 2.5 Ghz, 512 Mb nVidia, and 2 Gb RAM. I'm planning on using this as a Multimedia computer doing audio recording, video editing, and graphic art. I'll most likely be using such programs as Logic Pro, Final Cut Pro, Adobe After Effects, Photoshop, etc. I'm not really planning on any 3D modeling or gaming on this laptop. Anyone know if having more RAM or more VRAM would be better for this setup? I've looked everywhere but all I can find on VRAM is info on gaming benchmarks. Any help would be great.
