Considering an upgrade. If I go with enthusiast board it will be 1366 6-Core Extreme CPU, even though I would not have much interest in overclocking. If I go server board, it will be a Supermicro dual-Xeon server board that can handle the 6-core Xeons as a pair. Ouch on the price! Obviously, as far as the Xeons go, there won't be any overclocking, even for a few quick tests and such. In either case I will be running Win 7 Pro 64-bit as the OS, and the systems will be liquid cooled. I have the appropriate water cooling equipment, PSU's, ATX/E-ATX cases, etc. Any explicit advantage to either chip? I'm not an overclocker, but I do want speed at stock ratings. Are the Xeons just more heavily validated and tested? I have not ventured into the world of server boards a lot, but those I have used from Supermicro I really like since they allow so much greater control, such as BIOS-level remote desktop, etc.
