The main use would be school. I bought an under powered computer with a 1 ghz AMD dual core and will be upgrading very shortly. Your help is greatly appreciated.
The dual core would be better for you then. Are their any 2 specific laptops you are having a hard time deciding over? If you can link them we should be able to tell you which one would be better for your needs. While I said that the dual core would be better, that rule only applies if the CPU's are the same architecture. We will easily be able to determine this for you.
