Lastly, ditch the Nvidia Quadro -- it's only a PCIe 2.0 card and probably does not have a UEFI compliant VBIOS and therefore can't be used in UEFI mode at all. The motherboard BIOS will display a warning at POST telling you words to the effect of "No GOP driver detected. Replace GPU with UEFI complaint device!" That's the bad news. The good news is the motherboard defaults to Legacy/CSM mode so the Quadro will probably work at first boot and only if you stay in CSM mode. That's not wise. Specifically because your CPU has integrated video that IS UEFI compliant and Legacy/CSM Mode can severely hobble SATA and M.2 devices. Seriously, keeping the Quadro in is redundant. The IGP on the 5600g is more than capable.
