With any new computer you should get 4 GB of memory, the more the better. There are two version of Windows you can get 32 or 64 bit. The 32 bit version of Windows has a 4 GB maximum on the memory, the 64 bit versions go much higher depending on the version you get. 4 GB will give most people more than enough to do what they need. To see how much memory you currently have just Right-Click on the My Computer icon and select properties. In the window that comes up you will see the memory you currently have.
