Complete desktop system

This Dell OptiPlex 790 all-in-one integrates a 22 inch widescreen LCD monitor with the main unit for a compact footprint. An Intel Core i5-2400 quad-core processor runs at 3.10 GHz with Turbo Boost up to 3.4 GHz. The system includes 8 GB of DDR3 memory, a 500 GB hard drive and a 16X DVD±RW optical drive. Windows 10 Professional 64-bit is pre-installed along with a USB keyboard and mouse.

Home office and general use

The integrated graphics and single hard drive suit everyday productivity, web browsing and media playback. Buyers who want more storage or a dedicated graphics card for gaming should look elsewhere. The all-in-one design limits internal expansion compared with a tower chassis.

Intel HD Graphics 200

The built-in Intel HD Graphics 200 handles display output on the included 22 inch monitor. It relies on shared system memory and does not support modern gaming titles or GPU-accelerated workloads. This specification decides whether the system meets your visual-performance needs.
