graphic card for Gigabyte z97x ud3h!

[Adrian B]

ok! thanks a lot Adrian!
If I follow your advice:
"A fresh Sierra installation would be the best option. You can then use Migration assistant to move data across. Your important data should always be backed up anyway.

It will be ok for me or I need some others advices?

Should be fine - follow the guide (Install UEFI), if you run into issues or are unclear on something that you don't see an answer/description for then post in Sierra Desktop support for some assistance from the wider community. Good luck!
