Neither of them will run it on ultra, you need to be looking at r9 290x and 780 ti's for ultra
can asus r9 280x direct cu version or sapphire vapor x run it on ultra
No, watch dogs was very badly coded so even the 780 ti's have trouble running it on ultra, but the 280x WILL run almost any other game on ultra, but id depends on your cpu too
