Dell Optiplex 790
Let’s say it: the Dell OptiPlex 790 desktop is one of the best desktop computers you can snag on the market. We’ve long been impressed by the OptiPlex series, but this model takes the prize for the smallest--and highest performing--business PC on the market.
What You’ll Love About the Dell OptiPlex 790
The OptiPlex 790 comes in a businesslike facade with a chassis of sturdy sheet metal. That same workhorse persona shows through in its internal power too, with a 2.5GHz Intel Core processor with plenty of power for desktop applications, even if you’re drawing hard on the Wi-Fi or HD graphics.
Plus, the lightweight CPU gives you low power consumption, a major benefit in an office computer.
