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.
My favorite Gigabyte user quote: "My GA-XX-XXX-XX is AWESOME Best board I ever used, I can't wait till it comes back from RMA."
Not knocking them, just I have seen that a few times and always laugh :)
Glitch in the task manager? That is unusual..
Have you changed anything in msconfig? You can limit the number of cores in there...which is seperate from actual Hardware detection I believe.
SB is a nice upgrade actually, efficiency wise and feature wise (sata 6Gbps on ich10r ;) just for one...)
Having a X58 and selling it for SB is not a good move though... IMHO X58 is still a very powerful platform. Should have taken the 980X though over the 970 ;)
