While he is right that you may not ever need the CPU resources, the RAM I would argue is necessary (plus it's only $100 and will overall make a HUGE difference).

Ram is one of those things you can almost never get enough of. I am a heavy chrome user (and general system user), and I cringe anytime it's less than 8GB because it requires much more tab management for me. Which may be better for me to do, but I keep a large amount of misc work in various chrome windows and tabs, and closing it isn't necessary for me.

Along with that, I'm often running a bunch of other apps. CPU is never usually a problem, but RAM definitely is.

That being said, you're probably fine with the base model, but I certainly would at least max the ram. :)
