Hi all, I've decided to purchase my first Macbook. I've chosen Macbook Pro 13" with Touch Bar+Touch ID, but I'm torn between two options: should I choose the older model with a 2.9 GHz processor (i5+Intel Iris Plus Graphics 550) or the new one with a 3.1 GHz processor (i5+Intel Iris Plus Graphics 650)? I don't know that much about the specs of computers, thus I'm not sure what the difference would mean in my case. I would like Sims 3 or 4 (with most expansion packs) to play smoothly on it. Mostly, I just surf the net, download and watch movies. Generally, I work with Word and Powerpoint. I'm lazy about closing tabs, like to have a lot opened. Also, I'm planning on using this laptop for a greater amount of time. Another thing I've hesitantly considered: upgrading from 8GB memory to 16GB. Everyone suggests that it would be useful, but what about my particular case? Thank you in advance for the answers, all's valued!
