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.
General purpose desktop computer
These days, $500 to $1,500 will net you a desktop with a dual-core CPU and enough power to run productivity apps, view and edit vacation photos, manage MP3s and videos, and even play many of today's games--the core activities most common to families, students, and the general purpose PC user. At $1,000 and up, you should easily be able to perform those tasks. Spend around $500, and in most cases you'll still be able to run common tasks without delay, although 3D gaming becomes a stretch. You will definitely find a dual-core chip in a $500 desktop (you should insist on a dual-core chip these days, unless your budget keeps you under the $500 mark), but Vista could still give you trouble. Be sure the PC is equipped with at least 1GB of memory, and it's a good bet that you'll be able to smoothly run Vista. Add in a 128MB graphics card, and you'll get the Aero effects with little to no performance loss.

Home office desktop computer
Graphics are less of a concern for most businesses, unless you run a design shop. At minimum, you'll want a desktop computer with enough power (read: dual-core CPU) for multitasking your daily office chores. The money you save on the graphics you can put toward a larger flat-panel display and a better warranty. Vista complicates matters a little. Microsoft recommends at least 512MB of system memory and a DirectX 9-capable graphics card, and it ups the specs to 1GB of RAM and at least 128MB of independent video memory for Vista Home Premium with Aero. Of course, an iMac will get the job done, too, though at a higher price than your typical business PC.

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.

The central processor (CPU) is the heart of any computer system and the best test as to whether a desktop computer or notebook fits your needs.

| AMD | Phenom | Very high | Gaming and graphics |
| Intel | Core 2 Quad | Very high | Gaming and graphics |
| AMD | Athlon | High | Mainstream |
| Intel | Core 2 Duo | High | Mainstream |
| AMD | Sempron | Medium | Entry level |
