Unlikely for me. My 12.9 3rd Gen is still doing well. if anything, i'll spend the money on a battery replacement. Keep for longer. We still have the original iPad Pro from 2015. Used for 3 years until being replaced my 3rd gen. None of Apple's software nor any apps take full advantage of the CPU/GPU. Until there is a task that makes the iPad start lagging, that is when i will look for a replacement.
