TechPowerUp posted a review on the Zotac GTX 1080 AMP! Edition 8 GB
A quote from the article:
Zotac's GTX 1080 AMP! Edition is one of the more affordable custom designs, retailing $30 cheaper than the Founders Edition. The dual-slot, dual-fan card is still overclocked out of the box and comes with a good cooler that uses lots of metal, delivering excellent noise levels.Zotac GTX 1080 AMP! Edition 8 GB @ techPowerUp
