I might go the 16gb RAM route as all my computers lasts me around at least 3 years. However this will be my 1st mac computer.. (i only get laptops as i need portability but is my main computer as well.)

Another question is will 256gb of SSD be enough for softwares? Im planning to get the base model (upgrade to 16gb RAM) then buy either a thunderbolt or usb 3 external drive for all my other media files.

What do you think? Will the image editing software run a bit or a lot slower when getting the files from the external drive, edit, then save back to the external drive?

I will be a beginner in PP, never tried it before.

My usual use is normal everyday use, occassional gaming and now for PP..
