The limit of writes is not a problem; wear leveling mitigates any possible issues.
RAM disks are stupid. Windows can use available memory effectively without resorting to such hacks.
Mechanical hard drives are definitely the larger bottleneck. I would upgrade to an SSD before purchasing more RAM. As long as you have at least 8GB of RAM, save up for an SSD instead. I notice quicker build times (of my own small applications) with an SSD over more RAM. I do have 32GB of RAM as well.
