Sound Card Issues

[smmushfiqur256]

I was looking to open an youtube channel. I have a 4th gen Gigabyte H81M S2pv motherboard.
Now i need to buy a micrphone in and around 50 dollar. So my question is do i need a sound card for recording better audio or will the onboard audio is enough.? according to my budget i can afford a sound card of 35 dollar. Thanks in advance for your concern

you have hd audio on it already.
1.Realtek® ALC887 codec
2.High Definition Audio
3.2/4/5.1/7.1-channel
* To configure 7.1-channel audio, you have to use an HD front panel audio module and enable the multi-channel audio feature through the audio driver.
