What 3D operations does aperture do to 2D pictures? Please don't tell me that GPU is used for image editing, because it is not true. Yes, there were specialised graphic cards for Mac that had dedicated CPUs accelerating many photoshop filters, but it was back in early nineties and won't probably happen again. GPUs used in today's cards are used solely for 3D operations acceleration and won't accelarate image editing calculations.

Aperture actually mentions > GPU requirements in the minimum system requirements (IIRC it's a Radeon > 9600) If lightroom can run just happy on much lower spec Mac with Quartz enabled graphic card I can't see any reason why Aperture couldn't. For me it is rather Apple's politics to convince pro photographers to buy a new Mac. -- Balance is the ultimate good... Best Regards Sylwek
