My dad has a prebuilt PC with a GTX 1060 founders gaming at 1080p on fallout 4 and two of my mates game on prebuilt PC's with GTX 1080 founders. They have had no complaints about their hardware.
So yes get a founders if you want but the third party ones are stock overclocked and still cooler (MSI, Gigabyte, EVGA, ASUS & ZOTAC to name a few)
