Newbie with Nik and Aperture 3. I am going to order the new iMac. If the choices come down to getting a faster CPU or SSD, but not both. Which one should I pick to benefit Aperture and Nik plugin the most? Thanks for your advice in advance. Peter Liu P.S. I am still having problem with running SEP2 on my old iMac 2.8GHz Core 2 Duo. A3 always crashes when SEP2 starts. I never had any problem with the other plugins.
