I'd say cores/threads is quite important.
When I was five-boxing, with an i5-2500K (four cores, no logical threads), it was much worse performance then after upgrading to an i7-2600K (four cores, and four logical threads).
Going to an i7-3930K (six cores, six threads), allowed ten clients fairly easily.
In the case of Wow, CPU is more important than Video for a lot of the game effects.
The only elements which were really video dependent were: Shadows, Water Reflections, Spell Effects, Weather Effects, etc.
Almost every other setting was more CPU dependent.
That said, the bottleneck is still going to be video ram.
You need a minimum amount to launch a client, and even if you have everything on minimum once you reach whatever the video ram limitation is... that is the bottleneck.
I'd imagine, once you reach that threshold, having more cores is going to be a bigger performance boost than having fewer cores to play with.
But I don't really know a whole lot regarding the Xeon processors, so cannot comment on their relative power vs the gaming processors.
With gaming processors i5-2500K, i7-2600K, i7-3930K, etc... more cores was highly beneficial.
