Essentially when running these emulators, the Graphics Card is more important than the processor. Sure a processor with decent enough RAM is required, but if you want a game to run smoothly (and with good FPS), a good -> great graphics card is a must. With that being said, 3GHz should be good enough, however, I don't know what kind of graphics card comes equipped with the specific machine you're inquiring about.

@Crase
Wrong. In case of emulation, CPU power is more important because it does the most job when emulating another System.
A strong GPU is only required if you want to play games in HD and antialiasing.
