Wondering if my specs are good for the Elgato

I wanted to get the Elgato game capture card HD but I know very little about specs and requirements for computers.On the website the elgato says I need:

2.0 GHz dual core CPU and a sound card.

My computer says it's processor is :

Intel(R)Pentium(R) CPU B940 @ 2.00 GHz 2.00GHZ and I'm not sure if I have a sound card.Is there anyway to be sure if I meet the spec requirements?Link to the website:
