Normally a sound card will have some technical details about the values for load and input so you need to see that. Most power amps would have only a high out but some may have a monitor or line.
I will warn you that a normal sound card may not provide the real time you may want. There could be quite a delay if you need to both play and record. i use a line 6 product and it uses up a lot of processing time on a newish system in low latency.
