Personally, I would get an external SSD and try it on there first. At least it’s new enough to have USB3 ports. If you’re comfortable enough with it under the circumstances, you can put it on your main drive. But you may find you need to upgrade the RAM or that it’s just too much of a resource hog in the end? But even if you back away from 14, it’s always nice to have an external SSD kicking around. :)
