This is an EXCELLENT entry/mid level motherboard packed with the latest technical features, and at a VERY good price ($149) for what you get! Includes things like; (6) USB 3.0 ports, (2) SATA 3.0 ports, a PCI-Express 3.0 x16 slot, Intel's new z77 chipset (optimized for Ivy Bridge CPUs), an mSATA SSD slot (for a solid-state hard drive), an onboard 2-digit LED diagnostics display, an "all-digital" voltage regulator, and Gigabyte's standard dual BIOS chips. The board instantly recognized my Intel Ivy Bridge CPU with no problems. The mobo arrived pre-installed with BIOS version "F7", and I updated it to the newest "F17" BIOS with no complications. Gigabyte boards are among the highest quality mobo's on the market (IMO), and they have a long-standing reputation for stability & reliability. As a result, I didn't have a single problem on the build or initial boot-up. I have been building my own computers for the past 16 years, and have never had a single problem with Gigabyte motherboards. And with their new "Ultra Durable 4" construction features, (which are designed to fight against humidity, electrostatic discharge, high temperatures, and power surges), this is one of their best entry/mid-level boards.

Some Tips...
BIOS: The best and most reliable way to update the BIOS is with the "Q-Flash" option located directly within the BIOS settings (just press the DEL key upon first boot-up to enter the BIOS settings). The other option of updating the BIOS through the "Windows OS" can sometimes be unreliable. And for the "best" compatibility in flashing the BIOS with a USB thumbdrive (through the Q-Flash option), use a thumbdrive that is formatted to FAT-16 or FAT-32, and 4GB or under.

I picked up this board for my latest build which included Intel's latest Ivy Bridge i5 3570k CPU, and I must say that I am extremely pleased with everything that this board has to offer.

-I had no problems overclocking my 3570k to 4.5 GHz on this board.
-Outstanding power control/delivery: In terms of voltage this board delivers exactly what the BIOS says it does (I've had problems with other boards and power delivery when OC'ing).
-On-board power/reset buttons, BIOS switch button, and even a button to clear CMOS are all very handy. I feel much more comfortable clearing CMOS values with an on-board button rather than removing the battery.
-3D BIOS is very flashy and user-friendly. The mouse support is a great addition as well.
-Dual BIOS (via on-board switch) is a handy feature: if one BIOS is corrupted or irreparably damaged you can boot from the second BIOS.
-Supports up to 32 GB Dual Channel RAM.
-Many USB ports (14) and 6Gb/s SATA connectors.

-I've never tested this board's temperature, humidity, or electrostatic damage limits, but I'll take Gigabyte's word for it when they say that it's "ultra" durable.

-Honestly none that I can think of--this is the best MB I've ever owned by far.

BOTTOM LINE: This board is perfect for my current setup (see specs below), and it has more than enough features for my needs. I would recommend this board to anyone--A+ in my book.

My PC specs:
Intel i5 3570k OC'd to 4.5 GHz
EVGA GeForce GTX 680
Corsair Vengeance 8 GB (2 x 4 GB) DDR3 1600 MHz RAM
Crucial M4 256 GB SSD
ViewSonic 22-Inch 1080p LED Monitor (1920x1080)

Very nice board, very heavy and solid.

Built a system with this a couple of months ago, utilizing an Intel 3750K processor, 2x4GB G.Skill Ripjaws X memory, and a Sapphire Radeon 7850 PCI 3.0 video card hard-coded to GEN3 in the BIOS, along with two system boot drives in a RAID 1 configuration.

It's been rock-solid and stable, running Intel Turbo-Boost (set to take the processor up as high as 4.0Ghz from 3.4Ghz), with the memory running in Turbo mode with the XMP Profile enabled, and with the latest "official" BIOS (F11).

There was only one issue, which almost caused me to return the board to Amazon. When I first powered up the system (before installing the graphics card), I had the monitor plugged into the on-board video output. There was no video. The BIOS would boot up, and stop with what looked like diagnostic code "Ab" on the LED ("Ab" is "Detect SCSI Devices"), with the monitor saying "No Signal". I couldn't get into the BIOS.

At first, I assumed that the board was dead, and I'd have to return it. Then, some searching on the web revealed that "Ab" is often a mis-reading of "A6". "A6" is "BIOS is waiting for a command from the keyboard".

A little experimenting revealed that if I powered up the system with the monitor disconnected, got to "A6", and THEN connected the monitor, I would get video and could work in the BIOS.

This was inconvenient, but once I got my graphics card installed and connected the monitor to the graphics card, everything worked as expected. I considered knocking a star off for this, but decided to treat it as a minor startup transient.
