I bought into AM5 at launch for this reason. Ddr5 being "expensive" at the time is a drop in the bucket today. Planning at least once CPU upgrade this cycle. I actually bought a second set of ddr5 and m-ATX mobo before the price jump that'll run my 7000-series CPU in a SFF case eventually. Just need a video card to pair with it whenever I do upgrade CPUs in my workstation.
