Adding external ram to 2014 MacBook Pro I'm new to macs so please bear with me if I say something dumb.

I recently switched over to Mac, and purchased a new MacBook Pro, but found that the computer did not have enough ram for everything I am doing (large photoshop files etc.) I was wondering if there is any way that I could get external ram or some type of upgrade for my computer. 

Essentially, can I get an external ram drive, or should I go back and upgrade the computer itself?
The internal RAM is soldered to the motherboard (i.e. totally user-untouchable), but for external RAM, you're welcome to check out this article at your own risk.

UPDATE: After having done some research, apparently RAM disks are exactly the opposite of what I'd thought. They actually turn a segment of your RAM into hard drive space. It still promises massive speed boosts, though, so you should give it a try if you're up for it!
