A good amount of RAM could be any amount of RAM depending on what the user thinks is a good amount, depending on what they use their computer for. The normal RAM size that is used for a computer is 1 GB which is used to run basic applications on a computer. 2GB-4Gb is the normal size for a computer if you are planning on doing any gaming. In my opinion a good amount of RAM would be about 4 GB of RAM, because with that amount of RAM you can run every program on your computer very efficiently. Anymore more than that will not help you much, unless you do a lot of gaming.
