I have trouble deciding which one to get. I am a digital artist with photoshop and light video editing with FCPX and iMovie. I suppose 8GB ram is enough and I understand I can't upgrade to 16GB in the future, right? That sucks. If I want to upgrade ssd and ram, I would go with cmbp. rmbp is very tempting for me but will rmbp with 8gb will do for photoshop and FCPX? I don't know what to do. Money is not an issue.
