I wanting to upgrade to the AMD Ryzen 9 3950X 16-Core, 32-Thread. I’m going to upgrade my mobo at the same time. I’m not wanting to spend money on a graphics card if I can keep from it. Does anyone have a suggestion for something with integrated graphics? Or have a suggestion for a cheap graphics card that will handle 4K video? I don’t do any gaming. I just use the computer for productivity work and some streaming. Any help is greatly appreciated!
You'll need to buy a GPU. The 3950X doesn't have integrated graphics. Motherboards do not have integrated graphics, they just have the video output ports to be used by your CPUs iGPU.
An X570 motherboard would be preferable for thet 16c/32t Ryzen 9. I'd also go for something that's pretty high end in terms of power delivery, considering your CPU.
For your 3950X I'd suggest these:
ASRock: X570 Taichi
ASUS: ROG CROSSHAIR VIII Hero
Gigabyte: X570 Aorus Master
MSI: Meg X570 ACE, Meg X570 Unify
Some cheap graphics options would be an AMD RX 570/580/5500XT or the 1650S from Nvidia.
