Dell OptiPlex 790 Mini Tower desktop

This Dell OptiPlex 790 Mini Tower desktop arrives as a complete system with Windows 10 Pro installed. It uses an Intel Core i5-2400 quad-core processor running at 3.10GHz with 8GB of DDR3 memory. A 256GB solid-state drive and a DVD±RW drive handle storage and optical media. Integrated Intel HD Graphics 2000 drives the display output.

DDR3 memory ceiling and integrated graphics

The motherboard provides four DIMM slots, all of which are occupied by the installed 8GB configuration. Maximum supported memory is 16GB, so any upgrade requires replacing existing modules rather than adding to them. Graphics rely on the processor's integrated Intel HD Graphics 2000 engine, which shares system memory and offers only basic display capability. No internal expansion slot for a discrete graphics card is described in the specifications.

Replaces older hard-drive office PCs

This system replaces desktop computers that still use mechanical hard drives, delivering faster boot and application load times through its solid-state drive. The jump is worthwhile for users who need a responsive Windows 10 environment for web browsing, document work and legacy business applications. Buyers who want more storage capacity, discrete graphics performance or memory beyond 16GB should consider a different platform.

Questions about this item

Should I pick the 8 GB DDR3 configuration or upgrade to 16 GB for this OptiPlex 790?

The system ships with 8 GB DDR3 installed across four slots, leaving no free slots; reaching 16 GB requires replacing all modules with a 4 x 4 GB kit.

How does the i5-2400 at 3.10 GHz perform in everyday office tasks once installed?

The quad-core 2nd Gen processor runs at 3.10 GHz with a turbo range up to 3.30 GHz, handling web browsing, document editing and light multitasking smoothly.

What does the integrated Intel HD Graphics 2000 limit me to for display output?

The integrated GPU drives the onboard video ports; it supports basic desktop work and video playback but is not suited for gaming or GPU-accelerated creative workloads.
