I was just reading that the Xeon D is still 5.5x faster than the AMD Opteron A1100 (which does not have significantly better TDP) so it seems like Xeon-D is where it's at. http://www.anandtech.com/show/9956/the-silver-lining-of-the-late-amd-opteron-a1100-arrival http://www.anandtech.com/show/9956/the-silver-lining-of-the-... I built a home VMware server a while ago using a 4670T which has similar performance to a Xeon D but does not have ECC and tops out at 32GB. Works pretty darn well even with the multiple VMs I have running on it. I think I measured power consumption at the wall at 40+ish-55W so it's quite efficient.
