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.
Probably the Cat's 4.3 or the Omegas based off of that would be best, that's what I'm using. Although I have no real reference to compare the 4.3's to with older drivers since I just got my 9700pro, but I'd recomend you always try to use the newest drivers, and they seem to work fine for me.
*edit*
Accidently put Cat's 4.2, I meant Cat's 4.3.
