Asus lists a bunch of E5 v2 Xeons as compatible here:

Normal P9X79, same list:

The Intel spec doesn't even list Xeons as supported for the X79 chipset:

Officially supported E5 2660 v2:

Unknown E5 2660 v1:

The v2 has 'OS Guard', 'Secure Key', and slightly higher memory bandwidth. The newer one also lists not having TSX-NI, but neither do. The supported one has 2 more cores...
I found the v1 available for $120, instead of like $1k. Hoping for a cheap upgrade to PCIe 3.0
2660 v1 not listed:

2660 v1 listed as supported, so maybe the v1 requires ECC?:
