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 a suggestion, I did read OP, I formerly ran CF 6970's and my first driver install was corrupted, and i cleaned it out with driver sweeper and re installed and they ran fine.
Wrong, I have seen it many many times online, usually has to do with user error when installing or driver issues. First thing you try is uninstall,driver sweeper in safe mode, then re install latest drivers.
Only cure is an air conditioner, getting better coolers for your 580's is going to add even more heat to your room, the better your pc's coolers are, the hotter your room gets.
8 is more then enough, I run 12GB, and have never seen it over 6GB usage once ever. As for BF3 load times, SSD makes the difference, has nothing to do with RAM amounts/speeds.
