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.
For under 150 dollars, I strongly suggest and OC GTX 1050 Ti. You can run almost any game on high settings at 1080p. My recommendation is Zotac GeForce GTX 1050 Ti.
I think Geforce GTX 1070 8GB will be just fine for your needs. There is not much difference between GTX 1080 and GTX 1070 but there is a considerable price difference.
