TechPowerUp posted a review on the MSI GeForce GTX 1060 OC 6 GB
A quote from the article:
MSI's GeForce GTX 1060 OC 6GT is a cost-optimized custom-design variant of the GTX 1060, that still comes with 6 GB VRAM and an overclock out of the box. In our testing we didn't see much of a difference against more expensive custom boards.MSI GeForce GTX 1060 OC 6 GB @ techPowerUp
