Didn't get what you are asking? You are worried about the motherboard failing after a few years and not able to find replacement for it in future?
Yes.
This is the problem.
After 4-5 years, most processor's compatible boards are not available of good brands like Gigabyte/Intel etc.

Chinese boards last only for few years- mostly 1-2 years maximum.
