Very true, but it isn't FPS you buy a £50 soundcard for is it?

Unless an individual (not necessarily you) has a decent soundcard to hear the difference their opinion on this matter is worthless. I knew a few people who said their onboard sound was good enough for games and they are perfectly correct, it is good enough in that it does make sounds. The thing is that with a dedicated soundcard it makes much better, richer and clearer sounds with much better quality. I have tried my onboard sound on my ASUS P6X58D-E motherboard, it does not compare to the Xonar DX in either quality or range of sounds, and that is using the same speakers for both tests.

Ok, we get it. You don't see the need for having a soundcard because a possible loss in FPS would be minimal.... You are missing the main point of using one though.
