Compact all-in-one with 22" display

The Dell OptiPlex 790 integrates a 22-inch widescreen LCD monitor, an Intel Core i5-2400 quad-core processor running at 3.10 GHz and 8 GB of DDR3 memory into a single chassis. A 256 GB solid-state drive and a 16X DVD±RW drive provide storage and optical media access. Windows 10 Professional 64-bit is pre-installed, and USB keyboard and mouse are included.

Office and light home users

This system suits buyers who need a space-saving desktop for document editing, web browsing, email and video playback. The integrated Intel HD Graphics 200 and 8 GB of memory limit its usefulness for modern gaming, 3D rendering or heavy multitasking. Buyers who require discrete graphics performance, more than 8 GB of RAM or a newer processor architecture should consider other options.

256 GB SSD capacity and 8 GB RAM headroom

The 256 GB solid-state drive comfortably holds the operating system, office applications and a moderate library of documents or media files. Large game libraries, video project archives or extensive photo collections will exhaust the available space. Eight gigabytes of DDR3 memory handles typical office workloads and single-application focus, but runs out when many browser tabs, virtual machines or memory-intensive programs run simultaneously.
