DELL OptiPlex 790 i5-2400 8GB 120GB SSD desktop PC

Business desktop with 120 GB SSD

The Dell OptiPlex 790 is a compact desktop computer built around an Intel Core i5-2400 quad-core processor running at 3.10 GHz. It ships with 8 GB of DDR3 memory and a 120 GB solid-state drive for the operating system and core applications. Windows 10 Home 64-bit comes pre-installed, and a USB WiFi dongle provides IEEE 802.11n wireless connectivity. This configuration targets students, home-office users and small businesses needing a ready-to-run system for everyday productivity tasks.

Sustained office workloads with integrated graphics

The i5-2400 maintains its 3.10 GHz base clock across four cores without turbo boost, so performance stays consistent during long document editing, web browsing or video playback sessions. Intel HD Graphics 2000 drives a single VGA output for basic display needs; it handles 2D business applications and video decode but is not suited for 3D rendering or modern gaming. The 120 GB SSD keeps boot times and application launches responsive, while the DVD-ROM drive covers legacy media access.

Replaces older hard-drive desktops for snappier

Moving from a traditional mechanical hard drive to the 120 GB SSD delivers the most noticeable improvement in system responsiveness and boot speed. The 8 GB DDR3 allocation is adequate for typical multitasking with office suites and browser tabs. Buyers who need more storage capacity, discrete graphics performance, additional display outputs or newer connectivity standards should consider a different platform, as this unit relies on integrated graphics, VGA-only video and the supplied USB wireless adapter.
