Motherboard faulty, which should I choose?

[Realist Peter Pan]

As in the title, my motherboard is waiting to kick the shit, and I'm looking for alternatives to just do a swap out. I forget if I need to worry about my os or not when doing this... 

 

anyways I'm looking at replacing my current mobo with either of these two boards (or a suggestion by yourselves) I thought about replacing my current with a new one of the same thing, but It's just more expensive.
