Wow, you dont even know there is 6 core Xeons? there are 4 core Xeons..
the fact you are not aware that the silicon waffer are all the same REGARDLESS if Xeon or desktop tells me all i need to know with concern to your knowledge. (lack thereof)
the only Xeons that are not desktop parts are the itanium. AnandTech - Intel Core i7 3960X (Sandy Bridge E) Review: Keeping the High End Alive
to quote ""If you look carefully at the die shot above, you'll notice that there are actually eight Sandy Bridge cores. The Xeon version will have all eight enabled, but the last two are fused off for SNB-E"" end quote..

Xeon 3400-series processors based on Lynnfield fill the gap between the previous 3300-series "Yorkfield" processors and the newer 3500-series "Bloomfield". Like Bloomfield, they are quad-core single-package processors based on the Nehalem microarchitecture, but were introduced almost a year later, in September 2009. The same processors
are marketed for mid-range to high-end desktops
systems as Core i5 and Core i7.
Gainestown or Nehalem-EP, the successor to the Xeon Core microarchitecture, is based on the Nehalem microarchitecture and uses the same 45 nm manufacturing methods as Intel's Penryn. The first processor released with the Nehalem microarchitecture is the desktop Intel Core i7, which was released in November 2008. Server processors of the Xeon 55xx range were first supplied to testers in December 2008.
Gulftown or Westmere-EP, a six-core 32 nm Westmere-based processor, is the basis for the Xeon 36xx and 56xx series and the Core i7-980X.
Westmere-EX is the follow-on to Beckton/Nehalem-EX and the first Intel Chip to have ten CPU cores. The microarchitecture is the same
as in the six-core Gulftown/Westmere-EP processor,
The Xeon E5-16xx processors follow the previous Xeon 3500/3600-series products as the high-end single-socket platform, using the LGA 2011 package introduced with this processor. They share the Sandy Bridge-E platform
with the single-socket Core i7-38xx and i7-39xx processors
. The CPU chips have no integrated GPU but eight CPU cores, some of which are disabled
in the entry-level products. The Xeon E5-26xx
line has the same features but also enables multi-socket operation.

again as i said within the same die line (in this case sandy E) ALL processors are the EXACT SAME Xeon sandy "E" desktop and "E" - Xeon same period..
so an E5 Xeon is the same as a 3930 or 3960 or 3820. ARK | Compare Intel
the E5-1650 is the exact processor as the 3930k
the E5-1620 is the exact processor as the 3820
then you get into the Dual Xeon E-26xx series which again are the same silicon same waffer same die line as the desktop sandy.
only these have all 8 cores enabled finally (some are only 4 or 6 core)
due to the 8 cores enable they have to keep the GHz a bit lowered due to TDP.
E5 Xeons come in 4,6,8 core. as far as your 10 core 88xx series thats a 3 gen old westmere-EX processor. a 4 core E5 would kill that thing for most applications.
the E-46xx are for 4 processor servers and again are the exact same waffer/die line.
i dont care if you have a trillion $ lab you work in, the facts are the facts.
and its evident you dont know them..
FYI i also build and sell Xeons and servers, at the same time i talk 99% of the people who call about xeons out of it for audio/video as a single 6 core wil cream the Xeons all day long unless you get into heavy animation..
you may be a server guy a kudo's to you.. but when it comes to audio/video and whats best this you do not know...
