Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
If the digital connections are used, the quality of stereo output could be enhanced. If analog, then the quality will be the same. The digital connection would sound better because I would tend to believe that Logitech took more efforts to make a decent DAC stage than the MB manufacturer. You will not get surround output from games with a digital connection from that MB.
