[PD] Benefits of using an external soundcard?

[Mario Mey]

I'm using my integrated soundcard:

00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia 
(Intel HDA) (rev 40).

I know that Pd is processing on CPU and I don't need more than 2 inputs 
and 2 outputs channels. So... I "think" that there's no need to buy an 
external one.

Is there any benefit of using one?

I know that this USB soundcard is not a very good one... but maybe it's 
good for my economy. What's your opinion?
