The 12600k isn't exactly last gen when it was released a month ago. It destroys the 5600x and 5800x and uses about the same power as a 5800x. In fact hardware unboxed showing it using less when playing Cyberpunk than a 5800x. https://youtu.be/LzhwVLUVork?t=795

+1, but atleast the i5 even unlocked should be the same coolingwise as an 8700k ... anything that can cool 150-160w is fine.

they stoped making the chip like a couple years ago. if thats the same bdie finder i used toget mine there was only one type that wasnt priced high as shit

That`s a nice card, using one myself.

There are several points that could count into that decision atm.

1. There might be a new platform in 2022.
2. Electricity bill.
3. Re-usability (that would aim for the G series, but does not need a second GPU in case u wanna use the current in a different system)
4. Specs of the other components
5. the way you configure the games. Framelock at 60 / 90 / 120 MHZ refresh rate

There is an up and a downside to this. Besides the PCIe crap running atm 4th and 5th gen, this really gets out of sanity. Let alone that we still have no GPU that would max out a 3.0 x16 during gaming, we have Pcie 5.0 with intel now. Since all you stated would be gaming... I might think about 4.0 at best.
So we got DDR5 coming up. Expensive but very interesting Layout. Might even boost AMD further.
AM4 is running out and AM5 might be the next thing. No idea what they are planing to use as RAM there.
AM4 is really matured, so might be a good point to get the maxed out end of line CPU's. On the other hand, you never know, maybe they put in NAVI into the next CPU's that might change a lot of things.

I am using the 5600G as main rig atm and have not even installed the 1070 in here, runs just fine. Thx to the really nice bios features, you can actually lock down the overall power consumption. So the 5600g would be able to run at 35W, 45W and 65W Tdp. Results in a power consumption from max 80W at 35W TDP up to max 150W at 65W TDP. So you can pretty much config it all the way you want. At least in games, I noticed no significant difference and so I ended up running that thing at 35W TDP with powersafing profile. That makes this system consume about 30W during browsing, movies and office work. I measured what it pulls from the wall here ;) (monitor not included)

Not everyone will have a spare dedicated GPU lying around, so this might be a valid point for a kind of mini rig like a small ITX system or DTX like Desk Mini later on. Since the 5600G got a pretty good GPU onboard, that would even make a console like TV rig later on.

To pin point that thought, think of your monitor as reference point. Max resolution, MHZ supported. GSYNC / Fsync on board? Numbers are a fine thing to look at, but no point to get a system that runs with up to 300FPS, if you cant handle it at all. Besides, even though the 1070 performs well, it doesn't even show up in the comparisons anymore.

As long as you don't plan to run the GPU at full load all the time, you won't even really notice a performance difference in most AMD builds. I am comparing the 5600g to 3900x here. It all comes down to the way u want to utilize the system.

I have been using the 3900x as gaming and streaming rig at the same time. There was no issue running it at 45W TDP and still achieve 100FPS in Warframe during streaming. Yet, I got the 5600G as well and use that one as daily driver. Works for Streaming as well, but you do notice the lack of cores there. On the other hand, you can utilize the integrated graphics to deal with the render work, which empties the dedicated GPU for only gaming. So depending on what you get, all that really matters is how you are going to use it. At least in my area the 3600 is out of stock and the 5600X more expensive than the 5600G. Yesterday you could get 5600G for 229€.

Regarding the question if you wanna get more cores or not. The more, the better you can work - the more you get, the more it will pull, regardless if you use them all or not. A solid upgrade has always been quite in the middle, so going for a 8/16 system would be pretty much the middle ground of what you can get. Unless you don't plan on doing some workload that actually uses the cores you got, you will only waste money, with overpaying for core count you don't need and the electricity that comes with it. That's like getting a Lamborghini in 30 miles only area.
Currently we really got a fast and good growth in the performance again, yet it goes way to fast. So getting something that can be used in a different purpose does make the most sense, at least from my point of view. There might be the ultimate CPU for you in the next release, or you might just have missed the one you really wanted, because you waited to long.
There aren't that many games that will take full advantage of the more cores and most of the games will do good on either a 6 or 8 core. If it is about future prove... forget about that. With all the security holes that exist and pop up in media here and there, you should replace the system on a regular base, so planing on a system that should be lasting you decade and going all out on the Cpu makes no sense unless you can actually use that CPU to it's fullest.
Just look at the difference in performance between the 1600x and the 5600x. Buy reasonable and maybe one step ahead to get an extra year out of it. You can rather spend the saved money on parts that serve a real purpose, like putting it into decent Ram (32GB) or a 2TB SSD for your games.

Looking at your lib, the most played games, 5600G or 5600x will do just fine. Most of the games would even run on the integrated graphics without any issue.

If you go for a 5600G or 5700G CPU you might consider going ITX due the lack if Graphics ports on the other form factors. Aiming for a decent multi Monitor setup, you pretty much get anything you need from a Gigabyte B550I (very good VRAM as well can easily handle a 5950x) or if you don't care about OC the IGPU you could also go for a Gigabyte A520I (using that one for the 5600g build atm). If RGB is your thing, skip the A520I that is not working properly there.

If you are interested in some IGPU OC results Here you go:

On the lower end MSI B550M PRO-VDH, there's also version with integrated WiFi for slightly more. It has ok passive cooling on VRM, to the point it was able to hold 12-core just fine according to actual review (https://www.tomshardware.com/features/cheap-AMD-b550-motherboards-tested/5).
