Im sorry but please make sure you can back up these statements beyond "trust me bro"
The AMD Ryzen 7 5800X3D is the company's new flagship gaming processor. It introduces 3D V-Cache, a dedicated piece of silicon with additional L3 capacity. In our review, we're testing how much the larger cache can help intensive gaming workloads and applications and compare it to the Intel Core...

It was ~$150 cheaper than the "equivalent" 12900k/ks and not much more than the 12700k which both required DDR5 to really shine which was INSANELY expensive at the time in comparison to a performant DDR4 kit. Near release it was 2-3 times the cost for RAM alone plus then the motherboard replacement being another decent chunk of change especially ones focusing PCI-e 5 connectivity.
I can still pick up a 5700X3D for ~£200 which is the same processor with just a slightly lower clock bin. I cannot build any platform for that kind of money no matter what you say.
The Intel Core Ultra 7 265K offers eight strong Lion Cove cores, just like the 285K, and merely four E-Cores fewer, for an almost 50% price difference. Despite the "Ultra 7" branding it offers plenty of application performance that can beat even the Ryzen 9 9900X. Things don't look so good in...

Even now a 5700x3d is within 3-10% of equivalently priced options without the RAM/Mobo upgrade being needed at the moment and can either put those funds to GPU (which we all know are extortionate at the moment) or wait for both Intel and AMDs next gen offerings which should offer a decent performance upgrade vs current offerings.
So if you are on AM4 at the moment and have the ability/funds to upgrade to a 57/5800x3D but they dont stretch to a full rebuild you are mad to think of any other option if they are fairly focused on gaming. You do not however build a new AM4 rig in the TYOL2025 as there are better options out there both from Intel and AMD in everything else.
AMD has more longevity as you should still have at least one more generational upgade on current AM5 and their current options are one of if not the best option for gaming and they arent a slouch in productivity either.
Intel has SOME interesting options from things like 14600/14900 depending on what your focus is and the Core Ultra stuff if you are purely productivity focused but you have the knowledge that all platforms are EOL with no real upgrade options puts me off advising investing massively in either of their options.
