I have two Zotac GTX 1060 AMP cards and two RX 480 8GB from different brands on the same system. Form my experience, I would say do not mix Nvidia and AMD if you are not savvy enough to troubleshoot when problems occur. Here is a summary of what I have been seeing:
These points are specific to mixed mode.
Advantages of NV:
1. You don't need to connect it to a monitor to overclock or monitor the card for temps etc.
Disadvantages:
1. Driver may crash if you close and open the miner for any reason or use a different to mine another coin. Sometimes, you don't have to restart the PC, just reapply settings using Afterburner. But most of the times, you have to restart the PC to use the card again. Windows 10 seems to be better than Windows 7 when it comes to handling driver crashes. 2. The PCIe x1 to 3 X1 switch multiplier (One you use to connect three cards in one PCIx1 slot) does not support Nvidia cards.
Advantages of AMD cards:
1. Driver does not crash often. Even if it does, you can reapply settings with Afterburner without restarting. 2. You can use the PCIe X1 multiplier.
Disadvantages of AMD cards:
1. Must be connected to a monitor or a dummy plug for Overclocking, tuning, and monitoring to work correctly.
If you use Sgminer or any of its variants (like garelessgate miner) in a mixed setup, you may need to use the --gpu-platform {0 | 1} option so that it detects the right GPU. Few miners like Claymore eth miner have the capability to handle mixed mode correctly.
If you absolutely have to go for a mixed setup, be prepared to troubleshoot.
