Dell OptiPlex 790 USFF All-in-One PC

The Dell OptiPlex 790 USFF is a compact all-in-one desktop that integrates a 22-inch Dell UltraSharp 2210t display with a 1680 x 1050 resolution. It runs on an Intel Core i5 quad-core processor operating between 2.50 GHz and 3.10 GHz with Hyper-Threading and 6 MB Smart Cache. The system includes 8 GB of DDR3 memory, a 500 GB hard drive, a DVD-RW optical drive and Windows 7 Professional 64-bit pre-installed. A USB keyboard and mouse are supplied in the box.

Suited for office desks needing a tidy.

This unit suits users who want a ready-to-use desktop with a built-in monitor, legacy optical media support and Gigabit Ethernet for wired networks. It is not for buyers who need a dedicated graphics card, modern high-speed storage interfaces, additional internal drive bays or a current operating system with ongoing security updates. The integrated Intel HD Graphics 2000 and DDR3 platform limit expansion for demanding creative or gaming workloads.

500 GB hard drive and 8 GB DDR3 handle everyday

The 500 GB hard drive provides room for documents, spreadsheets and a modest media library while the 8 GB DDR3 memory keeps multiple browser tabs and business applications responsive. Performance runs out when working with large video projects, modern games or virtual machines that demand more graphics power, faster storage throughput or memory capacity beyond the fitted 8 GB. The DVD-RW adds flexibility for archiving to optical discs.
