Questions about this item

Should I pick the 8 GB DDR3 option or look for a larger memory kit?

The system ships with 8 GB DDR3 installed; the OptiPlex 390 supports up to 16 GB total across its four DIMM slots.

What does the i5-2400 3.10 GHz quad-core actually deliver in daily use?

Four cores at 3.10 GHz handle office suites, web browsing and light multitasking smoothly; heavier workloads will hit the CPU ceiling.

How does the Gigabit Ethernet port limit my network speed?

The onboard Gigabit Ethernet caps wired throughput at 1 Gbps, so faster ISP plans or local transfers will be bottlenecked at that rate.
