Everything has to be taken within a context of what is going on around the usage and how well we expect someone to be equipped to deal with and isolate isssues.
The first board I looked at "trying" to find suitable $100 mobo shows what we are trying to say about suitable for overclocking in the overall scope of doing so.
The second board shown is one we have seen a lot here in the forums. It seemed to do pretty good. Maybe the cons is from a 'batch' of boards as can happen.
We know there are failures with anything in terms of just outright dieing. There are situations where bunches have the same issue and that can come from a running hardware change of parts used to make a product.

Pros: None
I learned to read into products before I buy them.
Cons: From the very beginning when the board was first released I had issues, first i had to swap another processor in to update bios, to one that supported the Fx 6100. (pain in the buttox) Then after a full year of stability issues, and upgrading parts trying to get the system running smooth new drivers nothing got better things got worse.
You can't overclock at all anymore or you will BSOD, wasn't able to in months anyways... You can't overclock you CPU or GPU.
Other Thoughts: Buy a proven brand, read into it, and don't waste your time with this board.
Says 8 core ready on the box... that was some B$
Cons for this board are within the first 7 or 8 user reviews.
