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.
I have a 9800GTX2 and a 8800GT in one machine. For the last 2-3 days when I run all three clients, after a few hours, the two 9800gtx2 clients slow down from ~5000ppd to 500ppd.
The EVGA precision tool shows them running at 50-60% usage instead of 100.
