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.
It tricks your OS into thinking you have dual processors (virtual), allowing your single processor to handle multithreaded applications better. If you simply go to Intel's website, you'll find a ton of information on it.
HT simulates dual processors, and provides somewhere in the 30% range in gain when an app that supports multi-threading is used or when doing a lot of multitasking.
