Hi all,
Trying to decide which route to go as they currently cost about the same on eBay, I can get dual L5630s (4 core, 40W TDP 2Ghz) or single L5640 (6 core, 65W TDP 2.26Ghz) for about the same price. They be be installed into a light ESXi host - running a few VMs, one of which drives a 3x10TB MDADM RAID6 NAS, some testing installs for various OSes and remote access Windows 7 instance.
Here's my main objects

Here's my main objects
- Idle power - I'm guessing single L5640 will get edge here, not having to idle 2 CPUs vs 1 as Westmeres don't have the amazing low power states that IV-B/Haswell chips do. This server is sitting around idle most of the time so this will have a big impact on power bill
- Cooling/Noise - I'm looking to passively cool the chips with CoolerMaster 212+ coolers, L5630 @ 40W TDP should be fine, L5640 @ 65W TDP might require some ducting
- Performance - Dual L5630 should have the edge here in multithreaded applications/VMs
- Expandability - L5640 would give me option of getting another matching chip down the road if needed for more performance
