I currently run over 400 GPU systems with PiMPs nvidia distro. This software is by far the most flexible I have worked with in a large scale environment. I have tried all other major mining distros and this is the one we have set as the standard for our machines. The support is top notch and any and all issues are addressed as quickly as one could hope for. The PiMP team is constantly working to improve all aspects of its product from documentation to the user experience to the core software package. No other product in this market can compare to the support you will receive from the team. If you are on the fence about this product, dont be. It is well worth the money.
