Ok, that's fine.
As for your questions, depending on the settings but no, a 960 won't max out Witcher 3 at 1080p, even a 970 struggles. It all depends on how many fps you are happy with and the quality of image. If you can afford a 970 then that's the way you should go, it's worth it compared to a 960. Asus is a better brand than Zotac, but to be honest, I haven't heard of many Zotac cards failing. If they were the same price, get the Asus, if the Zotac is a lot cheaper, get it.
