ASUS B550-PLUS TUF AM4 ATX Motherboard + Ryzen 5 5600X3D + 16GB G.Skill Ripjaws V Expired

This bundle is a very good value if you are looking to build a brand new budget tier system for gaming. The 5600x3d is only slightly slower than the 5800x3d in gaming, but it only has 6 cores instead of 8. The best price the 5800x3d alone has been is $260, so this bundle having a decent board and ram for only $10 more is great as long as you don't need those 2 additional cores. Most games won't take advantage of more than 6 cores, but if you're playing the latest AAA titles it may become something of a bottleneck, particularly in the coming years as UE5 becomes more prevalent.
The motherboard is a lower-midrange am4 board with acceptable quality and features. For a budget build the average user should find it entirely sufficient. Here's a link to the spec page: https://www.asus.com/motherboards.../techspec/
The ram isn't very high end, but once again for a build of this tier it's perfectly acceptable. Additionally, ddr4 ram is very cheap, so if 16gb isn't enough, or you want faster ram to go with this budget build for some reason, you can always upgrade later.
Overall, if you're looking to build a computer only for gaming, and are on a very tight budget, this is probably the best value you'll find.

Most people don't need 32gb of ram & the 5600x3d competes with even top tier cpu's when paired with a 4090 in certain games & it's not going to turn your system into an inferno and be a power hog which makes you sink more $ into your psu & case/HSF/AIO/Fan budget!

And where in the world are you getting your bundle prices from? I'm seeing $447.99 as the current price of the I7-13700K bundle

Edit: nvm price went back up to $499 for i7 bundle

Here's a link to hardware unboxed comparing the 5600x3d and 5800x3d with a rtx4090 across 26 different games at 1080p, 1440p, and 4k: https://www.youtube.com/watch?v=kpG4UoWihEg
At 1080p using a rtx4090 (the best case scenario for performance scaling to be shown, and an extreme example for a low tier set of last gen components like this) the 5800x3d is on average 6% faster than the 5600x3d in average fps, and 5% faster in 1% lows. The actual performance delta when paired with a more rational gpu, like say a 6800xt, will be significantly lower than that already minor 6% difference. While there are certainly games that will be bottlenecked by only 6 cores, that is currently more the exception than the rule.
With regards to streaming and processing video, you are correct that a 6 core cpu becomes a major limitation. That being said, if your use cases are more cpu intensive than simply gaming and you're building a new pc, then the last gen x3d chips on the dead end am4 platform aren't a good option period. If you require high multithreaded performance, you'd be better off looking at either intel 12th gen or later deals, or amd zen 4 deals.
Creating a computer with a similar (likely lower end but still acceptable) motherboard and ram and the 5800x3d would probably cost around $100 more assuming you bought all the components at good sale prices. At this price tier, putting an additional $100 towards the gpu as opposed to the cpu would yield an improvement in fps far superior to the difference between the 5600x3d and 5800x3d.
