Solved! Acer E15 Upgrading.

Solution
SSD upgrades improve pretty much everything in the system, outside of gaming performance. You would want to get the RAM changed to dual channel for best performance. Replacing the 2gb stick with a 4gb one should be pretty good, no real need to install 16gb in that system. With an i3, no real video card and low resolution on the screen I don't see what you would be using it for that would need 16 gb of RAM.
