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.
Just like a P4, you should run with -advmethods, but I'm not sure if the 4.0 client needs -forceSSE since I think it defaults to using SSE instrusctions on P4/Pentium M. You can put them both on there if you want to, but you can also just check your log file to see if the SSE boost is in effect already.
