I certainly wouldn't. The price isn't worth it for minimal benefit. I assume he wants to do various shit on a single PC (at the same time), so then that'd be cool (higher memory capacity (><mb), the cores, cache, etc.).
As an example, my preference is 1 PC, for power/heat/maintenance, for multimedia sharing/serving, server apps, development, VMs (generally for testing dev work, but also some services), and gaming. It's just better than having 3 or 4 or 5 sitting around.
Another thing, is keeping in mind how many bots he wants to run.
At any rate, if you just want a gaming PC and you aren't going shit crazy with number of tasks (i.e., a typical user), then no way in hell would I get a xeon - LOL. I save my money and get top end i7.
