Right, so my brother and I have the Digitech RPx400 floor processor which is supposed to have great computer connectivity. My brother is getting a new PC now, and was looking at better sound cards to aid with this. What we're trying to figure out is what he needs to be able to record directly into his future sound card with the floor processor. I've heard of people literally not using an amp or any microphones and recording directly into their PC, but I'm still confused on what hardware you need for this.

For references:

One sound card he was looking at - http://www.newegg.com/Product/Product.aspx?Item=N82E16829121006

The other sound card he was looking at - http://www.newegg.com/Product/Product.aspx?Item=N82E16829102006

He is a gamer, so I was already leaning towards the Creative X-Fi card, but my other audiophiliac brother suggested the M-Audio one.

Can anyone clear this all up for us?

In summary:

He wants to be able to record with his guitars with ease. I'm pretty sure his pedal helps with this significantly, however, if it doesn't, what does he need? Or, if his pedal does help, does his choice in sound card really matter in the end?

Thanks!

I use the X-Fi elite pro as a recording interface and it's great! There's three modes : Recording / Gaming / something else. X-Fi really makes a difference in games, and the sounds quality is crystal clear.

I love it to death.
