I know this question had been asked many times but I just wanna know if it's worth it on my MacBook Pro. I have an early 2011 15 inch MBP: 2.0GHz, 500GB HDD, 4GB RAM and AMD 128MB graphics. Should I upgrade my RAM to 8 or 16 GB? I don't know if it's worth it because my Macbook Pro uses a 1333 ram instead of a 1666 one?.. And will there be any significant difference between 8 and 16? I surf the web and I play games like Sims 4 and I just do some nifty video editing with AE (I don't mind waiting for longer renders). (I am currently planning to buy a MBP Retina but I'll probably wait till next year or 2017 :l ) And should I upgrade to an SSD? I think it's pretty expensive and my MBP connects to it via a SATA cable right? Which is a lot slower than PCIe.. I saw this somewhere in this forums. How much incremental speed I can expect if I change my RAM and my SSD? I'm new here and thanks for reading this! Hope you guys have a nice day! I'll appreciate your opinions a lot.
