This is by far the best upgrade I've made to my Ender 3 Pro. With this updated motherboard I was able to use the Klipper firmware to achieve print speeds of 250mm/s at a much higher quality than I was previously able to print at 100mm/s on the original 8-bit motherboard with standard Marlin firmware . Both speeds were used with BLTouch so you may not be able to get prints as fast without BLTouch, but you should see similar improvements in quality and speed.
