Verdict: Is It Worth Downloading?

Yes – if you must use Windows 7.
The OptiPlex 790’s Intel 82579LM is a rock-solid Gigabit controller. Dell’s final driver for Windows 7 (2015–2017) is stable and reaches full 1 Gbps speeds.

But a warning: Windows 7 is end-of-life (no security updates since Jan 2020). Using it online is risky. If possible, upgrade to Windows 10 or 11 on this machine (Dell provides drivers for Win10 as well). If you stay on Win7, combine the driver with a firewall and an updated browser.

Final rating for the best free driver: ⭐⭐⭐⭐ (4/5)
Deducted 1 star only because Dell’s website search can be slow – but the driver itself is excellent.
