Tough choice, stay with AMD system or Intel build

Hi guys, yesterday i just won a giveaway of a brand new I5 14600K. The problem is im using the AMD system:
B450M ASROCK Steel Legend
Recently upgraded used R7 5800X3D
EVGA 3080TI FTW3
Ram is 8Gb x4 DDR4 3200
Pls note that im not in the US so price of new components might be 5-10% more expensive.

So in order to use this new CPU, i have to buy new Mainboard and according to my friends, new DDR5 of atleast 5200 or 5600. Im thinking of Z690 chipset not Z790 since i really dont need the newest thing.

Im mainly a gamer but i might step into rendering soon, so if you guys are in my shoes, should i stick to the AMD system or sell the AMD sys and go for a new Intel build? Thanks alot guys and have a nice day :D
