Anyone old enough to remember when PCs would try to use their buzzer speaker—the one meant to give audio feedback on motherboard errors—for in-game audio will know the value of a basic pair of desktop computer speakers. Even though we no longer need to plug soundcards into our gaming machines, the ability to output music that doesn't sound like a horde of angry wasps learning to play the kazoo in a sex toy factory is important in a world where games have actual composers working on them rather than expressing themselves through a series of bleeps the programmer made up. No disrespect to Jeff Minter there.
Even having a basic pair of desktop speakers can elevate your gaming over hooking up to some earbuds via Bluetooth (or, heaven forbid, using the speakers built into your monitor). And the Creative Pebble Pro is most certainly a basic set of desktop speakers.
