So, seeing the replies, it's not worth it to get a faster kit because the difference is going to be minimal. I'm going for an AM5 system, so I just need to update the bios, put a new CPU and done, my problem was the RAM because they are getting really fast but in gaming they are not worth it, I'm doing some video editing but not always, and I have some patience, and I am editing with a 1333MHZ DDR3 kit with and old xeon that are limiting davinci resolve, upgrading will make it much faster and smother.
I agree there aren't too many titles, but there certainly are some. FF14 Online is a game I often play and it scales really well with memory OC's. That's mostly due to the engine being severely single-threaded in high player / NPC populations scenarios. Raytracing also seems to enjoy tight timings and high speeds, Spiderman RT is a really good example. But you have to be running something like a 4090 to ever see such benefits.
Honestly, if you're gaming my recommendation is to buy an X3D CPU. They don't scale nearly as much compared to their non-3D counterparts in RAM speed, because so much of the data being sent to the cores is stored on cache rather than RAM. If you're asking about the future, no one can tell you for certain what's to come, however: I see that L3 Cache sizes continue to increase. RAM is becoming less of a bottleneck over time. There are rumors of Intel bringing back an L4 Cache as well, though I'm uncertain if there's any engineering samples in the wild.
I wouldn't stress over RAM speeds, this is coming from someone who spent months trying to get 7200 MT/s stable. Like ir_cow stated, just purchase some inexpensive memory and call it a day. 2x32GB @ 6000. Use your system for 6+ years and be happy with it.
My AM5 system is going to use a Ryzen 5 7500f but seeing the benchmarks comparing RAM Speeds, there is no much difference, and when AM5 is getting replaced with AM6 or whatever wants AMD, we're probably going to get like a Ryzen 5 11600X3D(11600 because the next gen is going to be the 9000 series and AMD leave the 4000 series for the notebook sector and some low-cost CPUs with PCI3.0 and other cuts, the 6000 Series for the notebook sector only and the 8000 series for the G series and again the laptop sector) or maybe even a 13600X3D if AMD can and wants, or if I get a decent B650 or wait until the next AM5 motherboards I could get upgrade to a Ryzen 7 11800X3D without a problem. But talking again about RAM speeds, seeing what you're saying makes extremely fast RAM unnecessary.
Yes, but really it doesn't in the grand scheme of things. If you are doing large compute projects, more memory outweighs faster. 12:27 (8000 MT/s) vs 13:03 (4800 MT/s). If I need 128 GB, that isn't possible on 8000 MT/s

Edit: To be clear, I would rather buy "slower" memory and put that saved money towards a faster graphics card for gaming.
Although I'm doing some video editing, I don't care about if I'm going to lose some seconds, I just want to get a modern system with good specs, so I don't need to upgrade every 2 years, I'm going to play primarily the Doom series, like Doom Eternal, Doom 2016 (Don't have it but probably soon going to get it), and the next Doom games, they aren't RAM heavy, the only RAM heavy game that I'm going to play (really heavy on RAM) is Cities skylines 1, and even with that I'm not going to use like 300 mods and 5000 assets at once.
I have a 75HZ monitor, so I can put V-SYNC (Free Sync if I get an AMD GPU, which is primarily what I want) and get the same FPS always, making a faster RAM unnecessary, I'm probably going to upgrade my monitor in a bunch of years, but even with that FPS difference is going to be the same taking what all of you are you saying.
Not sure what you mean by "worth it" in terms of an "old RAM module".
First, we must assume you are referring the same type RAM. DDR4, for example will not physically fit in a DDR5 slot. So if you mean hanging on to "incompatible" RAM, then no, not "worth it" if you can, perhaps, sell it.
Second, in most cases, more RAM trumps faster RAM. So if the old RAM module is still compatible with the rest of the platform, it may very well be "worth it" to keep it since replacing it (spending good money) with faster RAM may not yield any significant or noticeable (except on paper and benchmark tests) performance gains. If you cannot "see", in real-life use, genuine gains, then yes, it is worth keeping the old and saving your money for something else.
I mean with an "old RAM module", and old DDR5 kit comparing to the 11000 MHZ RAM that are probably going to exist, but with what now I see the performance difference is minimal.
But, it's worth to pay a slower RAM, like a 5600 MHZ CL 42 instead of a 6000 MHZ CL 30 to get that money in a better GPU?
