Do audio interfaces take care of CPU overruns?

[alphastew]

I have a laptop that I am using for audio creation through FL Studio. I've been looking into audio interfaces because when running more than one track, it sometimes has overruns. I've read that the interfaces do the digital processing. The only place I'm confused is that most people are using them to process instruments being recorded. If I am only doing work in the computer, will it take work off the CPU?
Any help you have would be great!
Here is the audio interface I am currently looking at.

I am not sure but I would say you are right in thinking that the interface would only help with DA conversion not internal to the PC processing. You may need a PC with more ram and a faster CPU maybe with more cores.
