@TorsteinH It is slightly off topic and the author of the topic will be receiving all the posts whether they are pertinent or interesting or not but …
Your 5700G is a bit faster than my 5600G (24544, 3282) versus the 5600G (19872, 3190) versus 5900X (39103, 3470) using the Passmark.
I feel that the 5600G was well matched to the 3060GPU and a nice change from my old i7-4790K.
The differences in CPU contribution to DxPL is like this (see snapshot below) where the NO NR figures are essentially free of any GPU involvement particularly with the 5600G and 5700G with their onboard GPU (no use for exporting but fine for driving the monitors)
This is for DP XD (PL7) for a batch of 40 of the Egypt image.
The 5900X has fallen in price since I bought it and can now be purchased for £199 in the UK.
But it may need additional cooling and may put the power supply under pressure but will improve one element of the DxPL export process and should help with editing activities and is certainly noticeable just doing any task.
In my case it initially went in with the 5600G cooler and a 550W Seasonic Platinum power supply and seemed fine but the CPU fan revved up while exporting so I replaced the cooler with another air cooled unit but with twin fans but the CPU is running hotter than I like, so I might have to rethink that!?
When I rebuilt the 5600G I decided that the power supply was too noisy and tried to buy a new Seasonic, as I stated above, and the upshot of that was that the 5900X now has a 650W Seasonic Platinum and the 5600G is back on the 550W Seasonic Platinum.
If you have the cash, and an adequate power supply and an adequate cooler then either wait for the price to fall even lower or take the plunge now but you might have to budget for more than just the CPU.
