I built my current home pc on the cusp of the transition of ddr4 to ddr5 and ddr5 was at the time out of my budget so I went with ddr4 and I can still play modern games fine with 32gb even at 2k. I might not max out everything but that was never a priority for me. Usually besides resolution I seldom touch the graphical settings if the game is running ok. In fact the only thing I upgraded one it until now was my GPU since that was a holdover from my previous one.

Home server also runs ddr4 and does ok, but that has been hitting more cpu bottlenecks now rather than memory.

That said its kinda sad personal users are getting tossed back a generation due to current generation ram being almost all gobbled up for AI.

I'm still getting by with a 6700k and 32 Gb DDR4. Upgraded with a recent AMD GPU it's a surprisingly capable gaming rig.
