TechPowerUp posted a review on the MSI GTX 1080 Ti Lightning Z 11 GB
A quote from the article:
Lightning is MSI's flagship card for the GTX 1080 Ti Series. Our review of the Lightning Z, which is the highest clocked variant, confirms it has the best cooler of all GTX 1080 Tis; delivering lowest temperatures and lowest noise at the same time. The Lightning Z is also the fastest GTX 1080 Ti we ever tested, but isn't exactly cheap at $999.MSI GTX 1080 Ti Lightning Z 11 GB @ techPowerUp
