|The performance Index is based on several components, not just memory. If you want a recommendation on what needs upgrading, you'll have to list your complete system specs.|
"The base score of your computer is determined by reviewing a collection of "subscores" assigned to various hardware components within your computer. Subscores are assigned to the following components:
* RAM random access memory
* CPU central processing unit
* Hard disk
* General graphics performance on the desktop
* 3D graphics capability
Your computer's base score is determined by the lowest subscore. For example, if the lowest subscore of a hardware component in your computer is 2.6, then the base score of your computer will be 2.6. The base score is not an average of the combined subscores."
