I used the speakers on two different PCs. One with a 700 MHz and one with a 800 MHz PIII. Maybe those CPUs were "too fast" to make a "fair assesment", but both PCs were used in normal every day cicumstances and there was no discernable performance hit on either.

If you'd like, and I got the time, I will run Evolva rolling bump map benchmark both with and without the speakers and let you know the results.
