Should I buy a GPU for a dual GPU dual boot, Or buy a powersupply for separate hackintosh

Main PC:

• Ryzen 5 5600X
  
• Nvidia 1660 super
• Works
• need to buy different GPU to hackintosh

Second PC:

• Ryzen 3 2200G
• iGPU
• Need to buy powersupply

I am not sure what to spend my money on and which will be easier. I am not experienced with hackintoshing but i am curious weather which would be better

I could either spend my money on a gpu such as a RX570 for my main PC or buy a powersupply and run the hackintosh on my other PC but it be slower

Would it be significantly harder to try make a dual GPU boot work rather than running r3 2200g with iGPU?

Which should i go for?
