Best Z77 mobo for 150

For under $150 would be Gigabyte GIGABYTE GA-Z77X-D3H which has digital power control for CPU, iGPU, RAM, and VTT. A comparable ASUS model costs $165.

what is power control for CPU, iGPU, RAM, and VTT? It is not listed on newegg specs page.

here is a asrock i found great mother board..

Just to refine question, here is what I think I need:

(1) Stability; support.
(2) 4 memory ports (32 GB total).
(3) a total of 8 SATA connections, including at least 2 SATA III.
(4) 1 or 2 eSATA ports.
(5) 2 PCIe 3.0 slots
(6) digital power control (??)
(7) of course, i7-3770 support (no K)

Anything else I should care about?

From what I could gather, and I seem to agree as it is what I will be getting, is the ASROCK Extreme6, it is about 160, the extreme4 is just over 130.
It looks to be an amazing board with everything you could need.

I am wondering whether H77 might be sufficient.
