Purchased this for the dedicated purpose of creating a self-contained lab with VirtualBox for CEH v10 study.  I regularly spin up 8-10 virtual Linux/Windows hosts and network appliances in a variety of configurations on this laptop, and it doesn't bat an eyelash from a performance perspective.  Super helpful to have this in a lightweight laptop that I can carry with me to practice/study wherever I'm at.  High performance at a very reasonable price.  This one's a winner, folks.
