Since the move to Apple Silicon you are realistically never more than 12-18 months away from a new chip generation in a MacBook. An M1 is still plenty good for the vast majority of workloads, especially if it's an M1 Pro/Max/Ultra.
Actually probably the best thing to do is wait until the M4 machines launch then bag a good deal on a clearance M3.
