What is wrong with your Z170x gigabyte?
had enough of all the software issues with it, not to mention it won't run PWM fans properly either. won't go into it here but i had lots of little issues with the board.
i am trying to get a refund or store credit atm with the supplier. they have it now again for the second time. they will of had it longer than i have since i bought it soon
If you have a modern motherboard, the on board audio is just as good as a dedicated card for the most part
sorry but i totally disagree with that statement, the on board sound on the Gig Gaming G1 was great yes, but it has a Creative certified Sound Blaster ZxRi 120+dB SNR chip.
using the same speaker setup, with an Asus Hero Viii the on board sound was pretty ordinary. i tried everything to try get it to sound ok. it was "OK" but the clarity and base just wasn't there for me.
hence why i added the SBZ card to the hero board.
for me the Asus on board sound probably would of been ok for just gaming, but i listen to a fair bit of music and it just didn't cut the mustard "for me anyway"
