Improvements will always depend on your starting point. The jumps between the X3D chips may not be as noticeable for some, but for me, still using a stock 5800X, the 3D version cost is within $50 of the 7800X3D. I’m missing out on DDR5 and PCIe 5, so I’ve been waiting to move to AM5. With the additional cost for the motherboard and RAM, I could go from a 5800X to a 9800X3D (assuming this will fill the gap) and expect significant improvements in my next system upgrade, which is exciting. I’m also just at the 3-year mark with my current system, except for the GPU, which I’ve upgraded.
