most of the people hate to go with gigabyte gpus because of their reliability
i will still suggest to go with sapphire
i heard many people had great success with sapphire itx
Sapphire 570 itx owner here. have three of these in my rig. purchase date jun 2017. last week fan of 1 of them started making loud whirring sound. two days later found fan completely seized and gpu throttling massively. so yeah 2 fans better than 1 if you can help it.
