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.
Overprovisioning is not necessary if your OS and filesystem are sending the TRIM command, and you don't fill your SSD up all the way with data. If you ever do notice that your writes are slowing down and you find that the SSD is nearly full, then just delete some files (say, so that you have 20% free) and empty the trash so that TRIM commands are issued, and the write speed should return to optimal.
Also, OP only ever really helps with write performance, and if you are primarily gaming, then you will be mostly reading.
