hi there, My current setup: - white macbook from 2007 (C2D, 2GHz, 2Gb RAM, 120 Gb) - firewire WD MyBook with my pictures - cheap Fujitsu Siemens 22 " L22W-3 monitor. I plan to seriously increase the number of pictures I take and edit in the coming months. But my Macbook is getting noisy when I work intensively and Lightroom is sometimes slowing down a bit. So I am thinking of upgrading / buying a home machine. The news setup should include or allow an upgrade to a much better display (NEC, EIZO..) Option 1: - iMac It would allow me some occasional FPS gaming, and I would finally throw this windows box, but I doubt the quality of the iMac panel, from the calibration/gamut point of view. Option 2: - Mac Mini: I can use my current display, calibrate it, and a bit later upgrade to a better external display (Eizo, NEC,...). But that second option is only valid if I can experience a performance increase... So my questions are: 1)what performance increase can I expect when switching from Macbook 2007 (Tiger) to Mac Mini 2009 (Leopard)? - for Lightroom management/editing - for other tasks (occasional video editing) 2) which Mac Mini config should I take? Thanks for any advice!
