What 8 core Xeon E5 v3 would that be? The 26xx's are hideously pricey,
and for a router, you're probably better off with something like a
Supermicro X10SRn fsvo "n" with a Xeon E5-1650v3. Board is typically
around $300, 1650 is around $550, so total cost I'm guessing closer to
$1500-$2000 that route.
The edge you get there is the higher clock on the CPU. Only six cores
and only 15M cache, but 3.5GHz. The E5-2643v3 is three times the cost
for very similar performance specs. Costwise, E5 single socket is the
way to go unless you *need* more.

With 24 million small businesses in the US alone, that's way too many apples.
