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.
The Gigabyte 8KNXP would probably work real well with Prescott. It is one of the most feature rich boards out and it will supply more stable power than any of the rest because of its DPS2 duagher addon card. It gives you a 6 phase total circuit design. The rest of the P4 boards out there are only 3 or 4 phase.
In the manual it says "Providing a more durable and stable power circuit to sustain a larger electric current up to 150A. DPS2 specially design for the future coming processor, which demands a higher working frequency and a more stable and durable power circuit."
