i just purchased: 27” 3.7 i5 580x 512 SSD 8 gb RAM I was going to upgrade some ram myself but wanted to see how much people suggest. I mainly do general computing, internet with a lot of open tabs, MS Office, YouTube, and some Lightroom and Photoshop (at an infrequent hobbiest level) No games or video editing Might do some home video editing in future—but nothing serious. I was thinking about buying 16 Gb which would be a total of 24 gb. I know people say you can never have too much ram. But I’d rather save the $100 if an additional 32 for total of 40 gb would be overkill. Thanks in advance.
