I have around $2400 USD I can spend on Amazon, any recommendations on the best allocation for it? Would I be better off buying multiple cheaper GPUs? Or spending more on a single more expensive one?
It's recommended to buy single more expensive because it will save more resources like POWER SUPPLY, RAM MEMORY and CPU.
Example x12 GTX 1060 you would need 2 rigs - 6 cards each rig but you would need to buy 2 power supply, 2 RAM memory, 2 CPU and 2 montherboards
VS
6 GTX 1080TI you will make 1 rig - 2 power supply, 1 RAM memory, 1 CPU and less cables in your home. You also need to consider the temperature 12 cards vs 6 cards + space in your room.
