In addition to the SDL sound offloading onto a second core and the potential for a dedicated server - client pairing, there can be a substantial amount of load at times on a system in the background and caused by the game. Graphics drivers nowadays are pretty multithreaded and you will find them putting a bit of load on other cores. 2 cores is definitely faster than 1 for Xonotic but beyond that it's unlikely.

A specific point on the current Haswell based Core i7: It's a waste of money for games in general. It's only advantage over an equivalent Core i5 is hyperthreading and games aren't that multithreaded. So, if anyone is looking for a CPU, save some money and get a 4670 instead of a 4770. Also ignore the K models unless you intend to do extreme overclocking - non-K models will still overclock within the kind of practical limits that normal cooling has. And for silent/low power builds forget about T and S low power models. They're a waste of money as you can undervolt normal CPUs to hit the same TDP.
In summary, don't spend any money ever.
