It's all gonna be fine. I used to have 2GB that came with the computer when I bought it back in 2009, worked flawlessly. No problem at all. I added extra RAMs for FinalCutX, Motion, and bunch of other stuff (also being able to run multiple apps at once.) It's only $60 for 8GB RAM. I remember it costing around $300-ish about a year and half ago.
