Business desktop with quad-core i5

The Dell Optiplex 790 is a business-oriented desktop computer powered by an Intel Core i5-2400 quad-core processor running at 3.1 GHz. It comes with 16 GB of DDR3 memory and a 500 GB hard drive. Windows 10 Pro 64-bit is pre-installed and a DVD-ROM drive is fitted. Integrated Intel HD Graphics 2000 handles video output via VGA.

Suited for office tasks, not for heavy graphics

This system suits users who need a reliable machine for everyday productivity, web browsing and legacy business applications. The quad-core CPU and 16 GB of RAM provide responsive multitasking for typical office workloads. Buyers who require dedicated graphics performance for modern gaming, video editing or GPU-accelerated workloads should look elsewhere. The integrated graphics and mechanical hard drive limit performance in those scenarios.

16 GB DDR3 memory installed

The desktop ships with 16 GB of DDR3 system memory already installed. This capacity supports smooth multitasking with multiple business applications open simultaneously. Memory type and capacity are fixed by the platform, so buyers needing a different memory generation or higher capacity must choose another system.

Questions about this item

How do I install the 16GB DDR3 memory in the Optiplex 790, and what is the common mistake?

The Optiplex 790 desktop has four DDR3 slots; install modules in matched pairs starting with the black slots first, as populating the blue slots alone prevents dual-channel operation.

Which component in the Dell Optiplex 790 will most likely need replacement after several years of daily use?

The 500GB mechanical hard drive is the primary wear item; its spinning platters and actuator arm degrade over time, so plan to migrate the OS to a solid-state drive later.

What performance limit appears first when the Intel Core i5-2400 runs sustained workloads in this chassis?

The integrated Intel HD Graphics 2000 shares system memory and thermal headroom with the CPU, so graphics-intensive tasks hit thermal throttling before the processor reaches its maximum turbo frequency.
