Basically you would be short-stroking it. This helps average speed because you're keeping the OS and most used files on the fastest part of the drive. It becomes impossible for any of it to fragment past the end of that partition.
I would do it if nothing else but for the sake of organization and ease of reformatting. Once you get in a habit of storing most of your files outside of the boot partition, "backing up" to reformat becomes a less-tedious task. The performance gain isn't going to be huge because the OS tends to be near the "front" of the drive anyway, but at least nothing will fragment or get rewritten to the slower areas.
As was said though, regular backups should be routine, and they should never be done to the same drive.
