You could run a single E5-2640v4 CPU which is 10 cores at 2.4Ghz and
90watts.

Dual 5620's are 8 cores at 2.4Ghz and 170watts.

** E5 v4 is faster clock for clock than Westmere, so the 2.4Ghz isn't
equivalent between the two CPUs.

It's somewhere between 2x and 3x more computing power than dual Westmere
5620's, and uses nearly half the power at full load.  In practice it
will use far less than half the power as E5 is much better at powering
down idle cores and so forth than Westmere was.  Not to mention single
socket, which will reduce your platform cost and power draw there. 
There's an additional win, in that FreeBSD doesn't scale well with
multi-package.

As far as motherboards there are a lot of choices,
https://www.supermicro.com/products/nfo/Xeon_X10_E5.cfm?pg=MB=SELECT=UP#List_MBD
shows a bunch of different PCI and SAS/SATA port and memory
configurations. Something in the X10SR family should work well for you.

That's the "less than half the power draw" option.  You can go with
something that has 1/4 the power draw of your current setup, but it will
likely be an incremental performance improvement (~25%)

We’ve had good experiences with Intel’s own servers based on the S2600Gx 
m’boards but might be overkill for you.
