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.
AMD or Nvidia video cards? More information would be helpful. If its Nvidia cards probably (no 100% sure though) and if its AMD cards 1 if you are lucky.
Zero is right. ATi with the new beta7 client still require a fair bit of CPU horsepower. Hopefully this gets fixed as the client matures but NV is the only way for you to go with that CPU.
