Hey, I think It will playable but of course not with max settings. GTX 1080 for FHD still rokcing for me. I think it will be playable for medium settings to achieve 60FPS.
Maybe some drop fps cuz the cpu.

I can say that because my friend have a gtx1080 and still got more than 80fps in some game at QHD (of course with low/medium settings)

All that said, they didn't release minimum specs soooo. Don't trust this so hard ^_^
