3900x does not have an integrated GPU,, only a couple of AMD cpu's do. Maybe you buy 2nd hand gpu card for now

@GeneralX Or this cpu... https://www.ebay.com/itm/AMD-Ryzen-PRO-4750G/293673898156 Unfortunately not so easy to score through more traditional channels. If it's anything like the onboard Vega in my NUC, which has only a 4-core cpu, the onboard Vega in this amd cpu should do quite well.

Hi Howard, thank you for your answer. This cpu would be nice, but it seems that the Ryzen PRO 4750G needs a radeon graphic card in the pcie slot, Am I wrong ?

I was looking a the AMD Rizen 5 3400G with vega graphic 11. Is it the one you have ?

Are you super limited in Vegas Pro with it ? ...because it does not meet Vegas Pro System requirements of AMD 3.0 Ghz and 8 Core minimum.

What about that setup for Vegas 18 ?

AMD Rizen 3400G
64 gigs of Ram (3200)
https://www.asus.com/Motherboards/ROG-Strix-X570-I-Gaming/specifications/
2 x M.2 drive

for now I would do basic video edition with it, This build would be later use as a secondary tower to only drive VST instruments and more audio outputs, This is why I am looking for onboard video card. I just need 1 pcie slot for my Audio card on a small size motherboard.

The main production tower will be equiped with a AMD 3950X + a RTX 2070 something like that.
But I have to wait for the new coming GPUs...

People testing this CPU have been using same test setup with 2080TI etc as they test with other cpu's. You would also have to ensure there's actually a bios for that motherboard that would allow using the new cpu.

That cpu is faster than mine. 4core - base 3.7, boost 4.2

Mine 4core, base 3.4 boost 3.8. You could do alot aided by GPU decoding, but with media that cant' be gpu decoded and requires cpu, would be more of a struggle. The real limitation would be with software encoding, if you only did hardware encoding like I do, it becomes more usable. You must check if vegas can even use the built in amd gpu's, either for decoding or as a normal gpu (compute) . I"M not in amd gpu or cpu world yet.

You need to check about compatibility with AMD IGPU, but if that works could be a reasonable temporary Vegas option.

I only skimmed the docs for the motherboard but it mentions it can use amd or nvidia gpus but nothing about requiring one to boot and it does list the 4750g on their cpu compatibility list for that board. Whether it actually works or not is a question for asus or someone who actually has one. Questions I would have specific to Vegas are: would Vegas see it? And if so, would it get confused if you had amd gpu in a pci slot? I noticed the i/o config in v17 and v18 doesn't let you pick a specific board for decoding like the video config does. If you had an amd igpu, might be a better bet to put an nvidia in the pcie slot. Fwiw the asus board I have with an hdmi port will boot without a pcie gpu and Vegas will run... not particularly well, however... it's an Intel igpu. The NUC has both amd and intel igpus and Vegas sees both of them.

Ok, thank very much Howard. I appreciate your infos.
