I am bit confused because I already have i9-9900K so should I go with AMD 5th gen CPUs or use my current processor, my main purposes are Gaming, editing, 3D model, streaming
You mean to say, I should use my current beastIt is unlikely that the new amd processor ,the intel 10th gen processors , or even the upcoming rocket lake processors are going to significantly improve what you do.
What are the rest of your specs?
How is your performance now?
Do you have any sort of a budget?
