Picking the Best iMac to Buy in 2020

[Haplodepatrijn]

If this 27 inch iMac will have a life span of 7 to 10 years, wouldn’t it be wise to opt for the 5700 xt gpu to be future proof. I’m into gamedev for desktop and laptops.

As u guys might be aware, AMD is going to release new graphics cards to combat against Nvidia new lineup. So can anyone tell me normally how soon will iMac follow it and update the graphics options? Paying 500 dollars for 5700XT didn't seem so wise now.
