Currently I am rocking this setup:

Nvidia GTX 1080

I have the posibillity to switch to a PC with these Specs:

R9 290
64GB DDR4 3600

The main things I do my PC is programming and video editing. I am using DaVinci Resolve, which heavily utilizes the GPU and CPU, would I have a disadvantage using the much older slower GPU, but with a much much faster CPU?

Or would editing be smoother with the much faster CPU?

I am editing mostly 4K:30 footage and rendering to 1080p:30 with basic color grading and effects.

    Since you're delivering 1080p, there's no need to edit in 4K. You'll get better performance in Resolve if you leave your timeline at the lower resolution, even if you're using 4K source footage. It automatically uses 1/4 debayer if you happen to be using RAW footage, and will use less resources for compressed codecs as well. Image scaling automatically uses highest quality available, too. But using a 4K timeline to edit will slow down Resolve and requires more vRAM per frame. Jul 6, 2020 at 16:12

From what I've read, Resolve very much depends on your GPU power -- speed and VRAM. I believe there's a preference to turn off at least some GPU usage, but that's probably more of a workaround for something crashing rather than something to be done on a normal basis.

Probably the best place to ask would be the Black Magic forums and over there, Carsten Sellberg answered a similar question with:

In Resolve the CPU is used to run the app, disk I/O and compression and decompression of codecs. Resolve does all its image processing in the GPU on the graphics card. More CUDA/OpenCL Cores are better.

There are two factors that is important for the Graphics card. The first is, that it have enough vRam to hold a single video frame. For 4K is the absolute min 6 GB of vRam, but min 8 GB of vRam or more are recommended.

The other factor is the CUDA/OpenCL performance. Higher CUDA/OpenCL performance gives a faster Resolve.
