That's up to you to decide ultimately. If your bios runs stably and there are no new features added you need, there's no real need to upgrade your bios. Remember that it's always a risk - if for some reason the upgrade is interrupted during flashing, your mainboard is toast (not really, but it's a hell of a hassle to get it working again).
However, I'm always living on the bleeding edge (as I'm sure many here are), and if I read about a new bios version, it'll be the first thing I do to download it and flash it into the ROM. As I said, you gotta decide yourself
