Looks like if your Computer can run Civ III it can probably run Civ VI. 8)
A great design is that the game allows people to play it in directx 9, 10, 11, and 12. Each all have their unique graphic capability.Not a bad thing. It's just good design and good business to allow everyone to be able to play your game.

It hasn't been announced yet but I'd imagine looking at the screenshots that if your computer can run Civ V it can probably run CiVI.
I believe minimum specs for Civ4 was below my specs
