CPU affinity performance gains

[informal]

There is a program that can permanently set affinity for any app. to the one(and the same) cores in the multicore(or multi CPU) system .It permanently modifies the .exe file and so it must be used with caution and backups are recommended (for the original .exe).
So you can use it and bind a single threaded game/app. to the say,highest clocked core in your Phenom rig .For multithreaded games there is no point in binding anything(but for single threaded,yes)

It's called imagecfg.exe and instructions are over here:
