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.
Just depends really. After reading around a many diff places I have found that the head room is not big on the 850's. They oc fine, but the 800 oc's better. And most 800 can reach 850pe levels, and tweaked you can easliy pass the 850 levels. Now with that in mind you could tweak the 850 and hope for the best. I kept the 800 and decided to tweak it. It worked out very well.
