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.
Buy used... you should be able to get an old 6870 or the like for ~$50ish and it'll perform better than the low end stuff. You might even be able to game at 1440p if you play at lowest settings.
I guess 1440p is 2K .. I have tested my R9 280 (hd7950) to 4K but it only has HDMI 1.4 which can only do 30Hz @ 4K and I need HDMI 2.0 to push 60Hz but I don't know if that is the same issues with 2K or not.
