Subject says it all. I'm considering building a system with one of these cpus. For those of you who have these cpus already, what have your experiences been with them?

Quick, practical context for before choosing parts: the Core 2 Duo family spans multiple steppings and die processes (the original Conroe designs and later Penryn refreshes). Later steppings tend to run cooler and support a few newer instruction extensions; some SKUs also include Intel 64 and VT‑x. These differences matter when sourcing a used chip or matching a motherboard, so verify the exact model number and stepping when comparing offers. For a model list and launch details see Core 2 Duo on Wikipedia.

Actionable build and buy checklist that complements points made by and :

  • Confirm the chosen motherboard explicitly lists the CPU (and stepping) in its support list and whether a BIOS update is required before first boot.
  • Reapply high‑quality thermal paste and inspect the CPU IHS and socket on used parts for damage; run a memory test (memtest86+) and a sustained CPU burn (Prime95 or similar) to validate stability.
  • If intending to tweak frequencies, favor boards with robust voltage regulation and clear FSB/voltage options in BIOS; otherwise prioritize stable, well‑supported boards and up‑to‑date BIOSes.
  • Check the SKU for VT‑x if virtualization is needed and verify OS compatibility for any modern software to be run on older hardware.

Practical expectations years later: Core 2 Duos still serve light desktop, retro gaming, and small server roles, but they predate many modern instruction sets and platform security features—so match the chip to the workload and consider a current low‑end CPU if modern app compatibility or security updates are important.

well each core is 1 or 2 ghz with 2mb cache on each core making it BETTER than a Pentium 4 3.8ghz with 2mb cache by about double

BUT not all programs (e.g games) even use the second core meaning for some tasks youll basically have a PC half the speed of a regular P4

If you're thinking about OCing them, you'll have to be very careful when choosing mobo. Some won't let you change things much. Friend of mine got dual core and his mobo (can't remember the name) gave him 2 choices for the multiplier setting. Pathetic.

Thanks for the input you two.
