Here is the reason why I don't go lap tops or Apple.
Micro Center had an AMD 12 core 24 thread processor, a 3900X for half price, at less than $300, add a mother board and you save another $20. I have all the memory and other parts in the original computer, so I upgraded to a hot little number for less than $500. The chip is last generation, and they are clearing it out, but hey it is a big upgrade for me and I'm going to be set for another 5 or 6 years.
I moved the MOBO and CPU to my rendering computer, and that was an upgrade. For free. The 6 core Ryzen and little stripped down board will become our entertainment (TV) computer. I had already upgraded the two newer computers to 32 gig ram and so I have 16 gig ram sticks for the "new" computer in the front room.
Thing is the next set of chips that will be introduced will use a new socket, new memory sticks, and will need a higher demand on the power supplies which will be an expensive upgrade, so I will do it now on the cheap and maybe skip a generation or two before I have to do a full rebuild again.
Oh and I forgot to mention, the rendering on BOTH computers is fast, the 12 core is insanely fast.
