Dell’s OptiPlex desktops are the optimum line for small to medium business users, especially thanks to the range of form factors that have replaced clunky machines across the country.

The OptiPlex 980 may not be the smallest daintiest desktop on the market but it definitely gets the job done and at full throttle.

What we like best

Business is all about productivity and the power you will find in the OptiPlex 980 will help you power through your workload. Inside you will find an Intel Core i5 or i7 processor that delivers a 35% performance increase compared to previous OptiPlex machines.

You can maximise efficiency with multiple screens with the advanced display capabilities. Thanks to the machines dual PCIe discrete graphics options you have support for up to four screens on the tower and desktop versions of the OptiPlex 980.

Older machines often have noisy fans, but the OptiPlex manages to minimise disturbances with its EcoKit, designed to reduce system noise by up to 50% so you can work in peace and quiet.

If you are wanted to look out for your company’s carbon footprint, this is definitely a machine that will keep your conscience clear. The OpitPlex 980 comes with Dell Energy Smart power settings and optional 90% efficient power settings supply units. It has an EPEAT Gold rating and is an ENERGY STAR 5.0 compliant partner too.

What we like least

One of the very few qualms we have with this PC is that it is not the most attractive of the bunch. It is simple and unassuming, but if you want a fleet of machines that will make your office look sleek and stylish then maybe this isn’t the PC for you.

There is an array of fantastic upgrades for these machines but they will you back a pretty penny.  Adding a 128 Gb solid state drive will cost you £269 alone.

The verdict

There is not a lot that can be said about this machine in a negative light. It is extremely powerful and has a great selection of ports and upgrade options (even though it will cost you) and it is eco-conscious to boot! It is no iMac in terms of looks but it had three great size options and would make a welcome addition to any office.
