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.
Recently purchased 2 corsair neutron gtx 240s and I am debating on raid 0.
Would it be better to just use one for OS and have the other setup for games/music?
780 ti for the sure, way better thermals and performance then the 290x.
If your not in a rush though you might wait til 800 series is released and see what they have to offer.
