I used this board for my first PC build and it was great. This board made my build extremely easy with some great features. If you are looking for a quality board for a decent price and you aren't into pushing your PC to the max or sli/crossfire then this board is for you. However, if crossfire/sli is your thing you probably want to go with a more expensive board.

SLI/Crossfire: While this is not a con for me it would be for many. While this board technically can be set up to do crossfire/sli, it really isn't the best board for it. It only comes with one PCI 3.0 slot.

SATA 3 Cables: It comes with 2 Sata 3 cables. Very convenient.
Layout: This thing handled everything my build took. My GTX 570 fit on this thing great without blocking any necessary slots (the usb 3.0 header was snug against my video card but not to the extent that it should be criticized). The fan headers were convenient for my case fans. I've seen several boards where if using a large video card you would have to not use certain slots or the fan headers were in the worst spots. Not with this board
Plenty of slots: 4 SATA 3 and 4 SATA 2 ports. Plenty of PCI slots to handle all of your needs
BIOS: This bios is the best I've ever seen. If you are wanting to overclock this thing, the BIOS could not make it any easier. It has a nice feature that allows you to pull up a virtual image of the board to allow you to see what is hooked up to what slot. THIS IS INVALUABLE TO FIRST TIME BUILDERS. This allows you to immediately see if any of your drives, video cards, audio plugs, RAM chips, etc are being recognized by the motherboard. In my first build, amazon sent me a doa solid state hard drive. I was immediately able to diagnose what the issue was.

this is the core of my rig. it has been a month since assembly without any issues. my main reason for choosing this mobo is that it has good spacing between the ram slots and the cpu. thus allowing installation of big after-market cpu coolers like the cm 212 evo presently installed. one thing that i noticed and researched is that the mobo do not beep once to indicate a successful post. it only beep when you enter the uefi bios. i like this new bios format. it is a good board.

Update 2014/3/21
Clean the tower n got message stating that CMOS or bios not configured. This happened before after I unplug it.I don't know why. However, CMOS battery was good. I smelt something burning. Unplugged PC. Mobo fried. it won't power up. Tried a new mobo with success. Thank goodness the CPU,ram,PSU or GPU not fried. I really liked this mobo. Don't know if I will get another. System i only setup 6 months ago.

I bought the AS ROCK LGA1155 Z77 Pro4 as a value pick to meet my needs.

I needed a slot that fit the i7-3770K and supported overclocking if I wanted to do that.
I wanted a USB 3.0 header for a front panel.
I wanted a PCI 3.0 slot for a single gpu.
I wanted at least one more PCI slot for a wifi adapter.
I wanted several SATA3 ports.

It meets all of these needs, and I got it for an excellent price.

- Lots of integrated graphics output options.
- Plenty of USB 2.0 slots
- USB 3.0 rear slots and header for front panel USB 3.0 slots.
- Several SATA3 ports, and comes with 2 SATA3 cables.
- Socket was very large. I installed a Cooler Master 212 Hyper EVO over my CPU. I installed my RAM first thinking that I might have very little room to maneuver under the large heat sink, but after installing RAM, CPU, and HSF, I was pleasantly surprised by the amount of space I had. I could definitely remove the RAM, and re-install it without much trouble.
- It fit very nicely into my corsair carbide 500R.

- Driver disk comes with a bunch of bloatware (don't they all!) but that's basically true of all motherboards. Look through it before you hit "install all".
- While this MoBo supports CrossFire, it only has 1 PCI 3.0 slot. I wouldn't pick this if you're looking for a multi-GPU set-up for gaming. I plan on gaming, but I don't plan on dealing with multiple GPUs so this fit my needs perfectly.
- It's pretty crazy that in 2013 it's still SO annoying to connect the power and reset buttons, leds, and HDD leds to the MoBo. I know this isn't just the MoBo's fault, but if case and MoBo manufacturers ever felt like sitting down and sorting this out, I'd be exceedingly happy.

Pretty much what you can expect for a budget board. Some problems here and there that will eventually get resolved but not too bad of a choice if you don't have money to waste on something like a sabertooth.

- Driver Issues. I installed all of the drivers straight off of the website and most of them seem fine except for my sata driver which was preventing me from starting windows (not even safe mode). I resolved this issue temporarily by switching the drive to IDE under the bios settings.
- Layout. If you plan on installing a large graphics card such as mine (listed below) then it will cover 3/6 of the sata drives towards the bottom of the board. This wasn't an issue for me since I still had access to the ports next to the RAM. So plan accordingly if you are thinking of setting up raid or you are using more than 5 sata ports.

- UEFI Bios is a great improvement for those coming from a "normal" bios. I don't have any experience with any other EFI BIOS, but I will say it's a big improvement.
- Price
- Lot's of port options
- Slight improvement in latency with xfast lan (certainly not 5 times faster than my last build.)
