I have the new mac pro with this settings:
3 GHz 8-Core Intel Xeon E5
64 GB 1867 MHz DDR3 ECC
AMD FirePro D700 6144 MB
Software OS X 10.9.2
And the AE performs slower than in my old mac pro. I have set the preferences as seen on all those tutorials on this site, I have an SSD external disc for cache files, memory and multiprocessing settings correctly...and previews are very very slow, and I can not even render a single comp without waiting 10 minutes. I am very disappointed and frustrated with this situation...
Am I missing something?
