Graphics card suggestions

[dpnptl]

Hey there, I have core i7 4790k CPU with gigabyte z97 d3h motherboard. Have installed MAC os Catalina which works totally fine. Now I want to add a Graphics card, so looking for a suggestion from the community. I am looking for a card that will work plug and play and won't break my current installation.

AMD, series depends on the budget, brands, msi, asus, gigabye, sapphire. XT 5600 and 5700 need to add agpmod=pikera as a boot flag.
