hey guys i am looking to purchase a new macbook pro and was wondering if it would be good to upgrade my RAM from 4gb to 8. I know i wouldnt use it right now, but on my first purchase i get a pretty decent discount so it would cost about $450 to double my ram. I have read that i probably would not use it right now, but i am working my way to do professional picture edditing. do you think that because of the price it would be worth upgrading? Thanks for whatever help and advice you can give!
