Honestly, I'm not sure what all this talk about parallel processing has to do with simply setting the CPU affinity. If assigning multiple cores from different CPUs to a single game client becomes an issue, then don't do it, but there shouldn't be any reason why you can't assign 6 clients to one CPU and 6 to another. As for whether it's going to work well or not, I honestly have no idea.

On the other hand, the 5820K starts off unlocked and capable of 3.6GHz minimum (which is already 20% faster than the turbo speed of the Xeon), and has the ability to push it over 4GHz with relative ease while on air cooling. A six-core CPU that is clocked ~50% faster than an eight-core is going to be faster in probably every benchmark you can throw at it."
This was a reply to a slightly different question about comparing a locked 2.1GHz 8-core Xeon and an unlocked 3.6GHz 5820K, but my reply would still partially apply if the OP was looking to use slow Xeons rather than those running near or above 3GHz. The OP is asking about a CPU which once sold for $1,500 not too long ago, and 2.6-3.3GHz is getting close to the stock clocks of the $1,000 5960X (3.0-3.5GHz). Unfortunately, I still think ~3GHz just isn't enough for running so many clients, because most consumer-level processors that we'd use for multiboxing run much closer to 4GHz when purchased retail, and then have the potential to overclock several hundred additional megahertz, whereas a Xeon doesn't.

Before I change it, see if you can change it yourself by editing the post, clicking on "Go Advanced," and then editing the title.
