There are three ways this can go. If your computer is in great shape both inside and out, and you don't have any speed or virus issues, stick with your current computer until you do have issues. If it is in great shape on the outside but is slow, upgrade to the Samsung SSD. Cheap investment for a potentially great improvement. If you feel like your computer has taken a beating and is past its lifespan, I would suggest a new computer, especially if you need it for work or use it extensively(assuming you can afford one right now). It all depends on how it is right now.
