Should I return my 5500XT and get a Vega 56, or even upgrade to a 5600XT or Vega 64

So I just ordered all the parts for my Hackintosh, and realized that I should have looked at the used GPU market since I can use the iGPU in the meantime. I didn’t think about this while I ordered the parts, and ordered a 5500XT as it fit within my budget. I will mostly be doing 4k video editing in Final Cut, and in the future will probably do some gaming on a windows install. But video editing performace is a priority. Should I get a used Vega 56 instead of the 5500XT? Or should I spend the extra $80-100 and upgrade to a 5600XT/Vega 64? It seems like the performance increase may be worth it. Thanks in advance.
