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.
I myself would go for a LGA775 processor. It's not that they are any better exaclty, but the upgrade path for the socket 478 processors is dead. 3.4GHz is the fastest you can install. (You can overclock to higher speeds of course) but the LGA775 processors come at speeds of up to 3.8GHz.
So for more flexible CPU support for the future I'd say go with LGA775.
