You MAY have problems due to having two graphics adapters, since PPro NEEDS to use the more functional NVidia instead of the lower power using Intel chip

Im having issues with Premiere I have the same specs but i have a i7 2.9 processor.
What kind of media will you be editing (file type and codec)?
Paul, mostly H.264 or MPEG-4. I some are in MTS AVCHD format. 1080 of course... I fail to believe that Macs are unable to use PPro. Im noticing the new Macs are using AMD Radeons (R9 M380 - M395). Macbooks look like they are still using Intel video cards.
