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.
My gtx 760 is starting to struggle with current games (witcher 3, xcom 2, the division beta),
would an R9 380x 4GB be much of an upgrade for 1080p gaming? Other specs are an i5 4670k and 16 GB of RAM.
