CNET editors' buying advice
We have not reviewed this product but here is CNET's buying advice on Desktops. This content was chosen based on the features included with this model of desktop.
Desktop computer memory size
One GB of memory is the recommended minimum to run Windows 7 and additional memory will make multitasking and graphics run smoother. Business workstations are apt to have a lot more memory to run industrial strength software. Choosing a lower memory configuration may save you money; however, most of the highest-rated desktop computers on CNET have 2GB.
