|The CPU & RAM are indpendent of each other. There is no RAM requirement for a CPU or CPU requirement for RAM. As stated above, the amount needed is determined by which OS & programs you're running, & the limitations of the motherboard. If you're running a 32-bit version of Windows, it's pointless to have more than 4GB RAM (some will say 3GB) because it won't all be recognized, but if you have a 64-bit version, you can run the max supported by the motherboard. You certainly don't need 6GB RAM for general purpose use (internet, email, word processing, etc) though.|
If you haven't bought the All-in-One yet, you should seriously reconsider. You'd be better off with a laptop/notebook.
