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 also have 3x 3007WFP-HC and a GTX 680. I've been doing a lot of research on this, and I thought I needed to get an active displayport to Dual Link DVI? I know you have SLI, but I thought that only allowed you to use the 2 DVI ports on one card, not both?
