Hello All, I am after some advice re the matching of iMac Mini spec to Aperture2. According to Aperture 2 specs, the new IMac Mini with 4GB/320GB is sufficient but it does not mention the 'NVIDIA GeForce 9400M graphics processor with 128MB or 256MB of DDR3' as an acceptable graphics card. Would appreciate if any advice from Aperture 2 users on this and if the proposed Mini spec is sufficient. I am an amateur photograher, on a limited budget, and I process mostly RAW photos. Do I need to go to IMac 2.6/2.9 to get realistic processing power? Many thanks.
