What is the difference in the rev.1 GA-Z87X-UD4H for GA-Z87X-UD4H rev.0?

[zov]

Hello! Thanks in advance!

Tomorrow, I'll buy mobo GA-Z87X-UD4H, but the store does not have the rev.1.

What is the difference in the rev.1 GA-Z87X-UD4H and GA-Z87X-UD4H rev.0?

Will I lose much buying rev.0?

Thnaks!
