Hey all, so i have 2 file servers and they are all kind of old and not very power efficient (they idle at like 370watt tower and peak at 600watt during start up). I also have a bottleneck and i think its the motherboard/cpu (Not enough bandwidth) because it struggles at lans when 3 or more people leech from the same array (drops down to about 20-30mb/s user, using 10gbe, on an 11 disk raid 5 array).
But i also want to keep it power efficent, these servers run 24/7 at home and are mostly idling. I'm Also going to kill off the second file server and attach its HDD's to the main fileserver via external SAS SFF-8088. Any recommendations for a cheap 6GB/s External RAID card/SAS Expander?
So for this build i want to go for a server CPU/Motherboard, i wouldnt mind getting one with the LSI2008 Chip, or 10Gbe Ethernet. Like this > http://www.supermicro.com/products/motherboard/Xeon/C600/X9SRh-7TF.cfm
But a big problem is i dont know which CPU are more power effecient, while still having good performance, Intel Xeon or AMD Opteron? The AMD Opteron EE and HE CPU's look nice and seem to have a low TDP, and are cheap. I read somewhere that the newer AMD Opterons have a power saving feature where it cuts power to cores that aren't being used? Or are there any Intel CPUs that are good low power usage and still good performance? any recommendations?

There both running Windows 7 at the moment, but i have a Windows Server 2008 R2 Enterprise key i can use when i upgrade, or i may be able to get a server 2012 key.
