Christian, please -- and this isn't completely related with coin mining -- if you have direct contact with Nvidia and Maxwell chip has indeed an ARM CPU, tell them to add an USB interface (or supply a separate USB hub that links to the first few PCI-e pins) and allow standalone operation. No motherboard, no Intel/AMD CPUs, no 4gb system RAM, no Windows. Just plug the PSU PCI-e power pins and the card boots ARM Linux from a connect usb pendrive
