Most motherboards only support a specific subset of CPU's. If you change your CPU you MAY need to replace the motherboard... but if you do that it will include the appropriate BIOS. You may also need to re-install the Operating System.

It's not. There are certain obstacles to upgrading the CPU (socket type, BIOS compatibility, cost effectiveness, etc...), but there are no inherent disadvantages to upgrading.
