Unless you are the type of hobbyist who wants the maximum overclocking possible, this board is the perfect combination of price and performance for the serious gamer. The layout makes installation a breeze, and installing a custom cooling solution should not present a problem in at least 90 percent of installations.

The bios is intuitive, and included software utilities are easy to use. Even the manual is pretty straightforward. All board connections are easy to make, and the layout is such that cable routing is extremely simple and effective.

Overclocking can either be done automagically, through MSI's OC Genie tool, or you can adjust just about every setting you'd like. I'm not an overclocker, so the OC Genie was just fine for me (and you don't even have to do that, if you'd rather keep your setup vanilla.

All in all, while you can certainly spend more, if you want an excellent ATX form factor motherboard, the MSI Z77A-G45 is a stellar choice.

When my P6T X58 decided to visit the silicone heaven, I decided to look around for a replacement and as you have guess.... there are not a variety of X58 to chose from... So, I decided to get me something new... because I needed to replace my CPU if I change the chipset from X58 to 1155, well, I decided to find the cheapest board with a modest CPU. I paired this MOBO with a 3570k and reused 4 DIMMS from my i7 burn build and it booted right on... I needed to clean install OS because of BSOD every now and then, because of the different chipset drivers, the BSOD appeared during intense gaming, after the clean install evrything is bread and butter... The board is very stable and the i5 is fast, not as fast as the i7 (just for a blink) but it did cost me $199.99 versus the i7 920 that was way much $$$. Whereas the i7 was idling during games or heavy usage, never exceeded the 12 %, the i5 is 70 to 86%, as long as the i5 never feels overwhelmed, I'm a happy camper. Overall I'm very satisfied with this build. The only cons for this MOBO are the lack of PCI and reset/power bottom or a POST LCD indicator, but for the price, you can't go wrong. If you are in a tight budget this is your ticket. My "New" build is a i5 3570k, MSI Z77 g45, Asus 570 Direct CU,4 DIMM (2gb) 8gb PNY XLR8, Ultra modular X3 850w inside a Obsidian 800D. Because I didn't have much time, I bought this board and CPU thru my local electronics store and paid a bit more than what Amazon is charging. The OC genie and the BIOS are the most user friendly ever, if you can understand English, then you'll OC like a pro...

1st go around with this new build...after frustrating 1.5 hours to trace a NOGO boot (shorted power supply to check electrical, checked connections, etc.) determined the MOBO was bad. Asked for RMA and Amazon did a 1 day turnaround with replacement. Now, great BIOS interface, a weird bulge on the back connectors (not a problem, just strange)...all good.

I'm usually an ASUS MoBo builder, but have tried 2 MSI boards in my last two builds (this one included). This board is straightforward, has plenty of ports for everything, and just works. I should note that I'm not an overclocker - so nothing in that vein was tested. I am hard on a machine though, using it for 3D modeling and animation (long render sessions), audio recording and editing, video editing, and some modern gaming. What it does do perfectly is handle an SSD via SATA 6gb/s, another SATA HD via SATA 6gb/s, and 2 more HD's via USB 3.0. eSATA works while all of these things are humming along at full speed. No real tweaks needed in the GUI BIOS (love it by the way) in the build. While this is simply doing what the board states that it will do, it is something that many ASUS boards seem to struggle with. Note that while these technologies (USB 3.0, eSATA, SATA 6Gb/s) are still being refined, it's about time that all of it can run together without conflict.

I would (and probably will) use this mobo again in an upcoming build. Nicely priced for what you get with your investment.

I was *fairly* rough with the board on the install, and everything still works perfect. I AM getting some wireless mouse keyboard lag, but no idea where to put the blame for that. Paired extremely well with the i5-3570k and the OC genie has it running at 4200.05 MHz not problems.

I used one board as the basis for a GPU mining rig as it supports more cards than most of its competitors. It ran faultlessly for months on end. Then I converted the rig into a desktop machine. I liked it so much that bought a second for another desktop machine and I am running that one with an i5. The second board was a refurbished item from MSI via amazon.

My only quibble is that, using the on-boad graphics with Win 7 there are some occasional sparkly pixels with some apps on the DVI port. I guess there is some driver issue there but it does not bother me.

One thing that I do like is that it works very well with the Win 7 power setting for entering and leaving standby mode.
