DELL 755/2.66/4/1T/W7P desktop PC

Refurbished Dell OptiPlex 755 tower

This refurbished Dell OptiPlex 755 tower targets budget-conscious offices and home users needing a basic Windows 10 Pro machine for web browsing, email and legacy business applications. The Intel Core 2 Duo processor runs at 2.66GHz with a 1333 MHz front-side bus and 6 MB L2 cache. Integrated Intel GMA 3100 graphics drive a single VGA output.

Upgrade from older Core 2 or Pentium 4 systems

Moving up from an earlier Core 2 Duo or Pentium 4 desktop becomes worthwhile when the workload needs 64-bit Windows 10 Pro and a larger 1 TB hard drive for local file archives. The 305 W power supply and four memory slots (all populated) limit further expansion, so the jump makes sense only if the current specification meets the task.

4 GB RAM and 1 TB HDD headroom

Four gigabytes of memory handles typical office suites and light multitasking, while the 1 TB hard drive stores years of documents and backups. Memory caps at 8 GB with no free slots, so heavier multitasking or virtualisation quickly exhausts headroom. The integrated GMA 3100 cannot accelerate modern 3D workloads or multi-monitor setups.
