Your PC is going to be great, I max overwatch and play it at 160hz 1080p with a less powerful machine than yours so youll be fine.
The brand or manufacturer of the graphics card doesnt really matter as long as they are trusted and the model is correct (1080,1070,etc)and it fits in your case.
I am a little bias tho, so I will recommend you find a card from either EVGA, Asus, or MSI as they have always treated me well in the past and have decent customer service and a good history of long lasting GPUs.

Your motherboard is a little expensive, which isnt a flaw or anything but I suggest getting something cheaper like a Z270x-UD3 from Gigabyte and buy a 120Gb SSD instead of a 275gb, with the money you saved you could probably afford a GTX 1080 which is a huge performance boost.

Besides that, its awesome and youll love it.

Hope it helps, good luck.
