The upgrade from a 3570K @ 4.2GHz to a Core i5 10400 offers noticeable improvements. You’re saving around $100 and will be using a 1080P monitor at 75Hz. Staying with your RX570 now makes sense due to availability, but you plan to move to a RTX 3060 Ti later. Running the 10400 at 2.9GHz versus the 10600K @ 4.7GHz will make a significant difference in performance. According to Gamers Nexus, the 10400 reaches around 3.6GHz all cores, so it effectively operates at that speed continuously.
You’d prefer this setup because the i5-10400 delivers peak performance when fully loaded at 4.0 GHz. The standard 65W rating isn’t sufficient for optimal results. You can adjust turbo limits via BIOS or tools like Intel XTU or ThrottleStop. If you’re using a GPU, consider the 10400F which skips the Intel GPU and may offer better value.
