I want a mATX mobo. Don't suggest a regular ATX mobo.
I have i7-3770k and intend to overclock up to 4.2 or 4.3 GHz, no more.

Both on Amazon and on Newegg, ASUS P8Z77-M gets excellent reviews, but ASUS P8Z77-M Pro consistently gets poor reviews. A lot of people seem to have issues with the M Pro related to clearing the CMOS in order to boot, or the board won't POST, etc.

I) Can anyone with actual knowledge of these issues related to the specific MOBOs I listed above comment? If you answer, please be detailed.

II) Any thoughts on GA-Z77MX-D3H or ASRock Extreme4-m?

I am really leaning toward the P8Z77-M pro, but really don't want to deal with boot issues, POST, and so on.

The mobos currently on the shelves should have or you can update to the latest BIOS, ver 2003, released last month that addresses the BIOS config
