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.
It sounds like a driver issue, the card keeps locking up.
Uninstall all the amd drivers, boot into safe mode and run driver sweeper :

make sure everything is removed and use the 12.2 drivers that naninani posted when you boot back into normal...
Are they having you pay for shipping each time?
I had a similar issue with a BFG 7800 agp card where they shipped me a broken replacement, I complained and they gave me a ups return label so I wouldn't have to pay shipping back again.
I think they are screwing you over, have you tried...
Cheapest I know if you have the adapters :

It's $30 per adapter though for mini-dp.
Otherwise adding a cheap pci-x card in addition will also work.
I've never been able to get all 5 outputs to work at the same time, it seems one DVI and HDMI is shared on my card (XFX 6970 2gb).
I finally gave up on this after reading AMD' spec which says :
"Native support for up to 4 simultaneous displays."...
