Sadly i can't go with the 7900X3D because i used programs that's very cpu depending "3dsmax , autocad, sketchup, etc" when it comes to cpu power , the 7900X3D falls shorts , tested it on my friend's pc and the results were not promising , i can finish and render work on my 13900K in less than half of the time 7900X3D takes.

In my opinion, Ryzen 7900 X3D is better, the price is cheaper and it has good performance, so there is no reason to buy 13900K!
