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.
290x over a 770 for sure. I'd still choose the 290x over the 780, especially if more games are going to end up like Watch Dogs. Also they are cheap now.
I've used both a 770 and a 290x (my current card). If you're gaming at or under 1080p, the cards are about even with the 290x edging ahead (except the 290x will use more power/run hotter); if you're running 2560x1440 or above, go for the 290x.
