Hi, I am looking to build a decent gaming/streams pc under £1000 as that's my budget. I will be using it for gaming/streaming and editing mostly. can anyone recommend any specs please.

so i have a aorus ga-z270x-gaming 7 intel z270 motherboard and no soundcard, i've heard that the onboard sound card crackles a fair bit, for gaming and youtube videos would it be best to go for a usb or 3.5mm headset and why/whats the difference? any usb headset recommendations?
