Question 1

How much does a Dell Precision 3640 cost?

Accepted Answer

The Precision 3640 runs $330 to $2,599 on Shopfox across 52 offers — deep fleet supply spanning base units to certified-GPU builds; the $400-1,000 band covers working-station value. GPU presence defines capability. Check its price history on Shopfox before buying.

Question 2

Can you upgrade the Dell Precision 3640?

Accepted Answer

Generously — standard DIMMs, multiple storage paths, and full-height PCIe graphics within the PSU class; the tower was built to open. GPU upgrades respect the power budget. Base-plus-upgrades remains the playbook. Compare live offers and seller ratings across Shopfox before deciding.

Question 3

Precision 3640 vs 3630 — which should you buy?

Accepted Answer

Two cores and a Windows path — the 3640 stepped from 8th-to-10th-gen Intel, adding cores and the official Windows 11 support the 3630 lacks; used pricing has narrowed to where the 3640 wins at parity. The 3630 undercuts at the floor. Both share the compact-tower formula.
